International Conference on Condensed Matter Photo-Physics 2020

ICAMP'20 is held in a split style, iCAMP’20 in summer and iCAMP’20 in winter. The former is an online conference and the latter meet-together conference. The meet-together conference will be held at a hotel Nen-Rin-Bou Takagamine Northern Kyoto which is located in a zone of fill in culture.

Online Discussion

M-01(Takaya Kubo, Prof.)
... Question-1 (Masao Kamada, Prof. July 7)
The author mentions that closely-packed colloidal quantum dot (CQD) assemblies work as light absorbers and carrier transporters. The enhancement of quantum effects in the dot is seemed to be against the carrier transportation. How does the carrier transportation possible in CQD?
... Reply:

... Question-2 (Masao Kamada, Prof. July 7)
The author introduces the high quantum efficiency, 47 %, of the solar cell at the first exciton peak. How does the exciton contribute the carrier transportation, in spite of the charge neutrality?
.. Reply:

M-02 (Masao Kamada, Prof.)
I, as one of the organizers, deeply appreciate your positive contribution to online iCAMP’20 discussion.
... Question-1(Atsuo Matsui, Prof. July 25)
I’d like to ask you about application of SOR (Synchrotron Orbital Radiation) because you have engaged in construction of SOR facilities for long. After the first facility was set up some 70 years ago, many SORs were constructed around the world for fundamental research, and maybe for application as well.
Nevertheless new SOR facilities are still under construction. For what purposes new SOR facilities will be used? Are they for application? If so, please enumerate the merit of construction, for instance, at Tajimi Japan.

... Qestion-1(Masaaski Uchida, Prof. July 24):
New QD which has high photoluminescence QY and high transparency in visible region is reported.
How do you estimate/observe the size distributions of dots and layers, especially of the ZnS:Mn layer?
... Reply( Sept. 18): The thickness of the ZnS:Mn shell layer alone has not yet been directly measured. However, we have confirmed from electron microscopy that the ZnSe/ZnS:Mn/ZnS QDs have a particle size of 5 nm while the ZnSe-core QDs have a particle size of approximately 3 nm.

.... Question-2(Ayane Murano. August 18):
In the absorption spectrum of ZnSe QDs, the absorption peak is observed at 3.5 eV. Why did this peak disappear in the spectrum of ZnSe:Mn QDs prepared from the precursor solution with a pH of 9?
.. Reply(sept. 18):
The spectral width of the absorption spectrum corresponds to the QD size distribution. In the ZnSe QDs prepared at pH 6, a clear absorption peak was observed because the size distribution is narrow.However, the ZnSe:Mn QDs prepared under alkaline conditions, the absorption spectra were obviously broadened because the size distribution was broad. This result is consistent with the results for non-doped ZnSe QDs [1]. [1] Y-S. Lee et. al., Chem. Lett. 45, 878 (2016).

... Question-3(Ayane Murano. August 18):
Why is the precursor solution used for the synthesis of ZnSe:Mn QDs better alkaline than acidic or neutral?
... Reply( Sept.18):
Several studies have reported that Mn ion is easily taken up under alkaline conditions[2,3]. The reasons for this are not entirely clear, but the difference in hydroxyl binding affinity to metal ions may give rise to different pH dependences with respect to the synthesis of semiconductor compounds[4].

M-04 (Yusuke Funakawa, M2)
... Question-1 (Piotr Petelenz, Prof. June 25):
As follows from the recent comprehensive overview [A.C. Berends et al., J. Phys. Chem. Lett. 2019, 10, 1600], CuInS2 is an electrically extremely flexible semiconductor. Its surface, and even its bulk electrical properties, sensitively depend on the surrounding medium. Is the choice of poly (diallyldimethylammonium) chloride for embedding the CIS quantum dots targeted for some specific application? Or is the environment it provides expected to give a cue for some fundamental question concerning CIS bulk physics? Or is this paper just a synthesis-focused reconnaissance study? I would be grateful for some guidance in this regard.
... Reply(July 10):
Dear Professor Piotr Petelenz Thank you for your informative comments on the manuscript. We really appreciate it. The purpose of this study is to fabricate a layered structure of CuInS2 QDs and to investigate its basic optical properties. It is usually difficult to deposit a homogenous film of water-soluble CuInS2 QDs. But by the LBL method a homogenous film of CuInS2 QDs can be fabricated, and they can be laminated one by one particle. Therefore, in this study, we used this method to fabricate a layered structure of CuInS2 QDs and PDDA.

M-07 (Yoshiki Tanabe, M2)
... Comment-1 (Tadashi Itoh, Prof. June 25):
Concerning the paper “Evaluation of photoluminescence properties of CdTe quantum dot superlattices”, I would like to send you my comments as follows:
(1) Congratulation for your success in fabricating CdTe QDSLs by utilizing the amide bonds between NACs which are the ligands attached to single QDs. It may be an excellent method for making regular QD arrays.
(2) You have successfully observed that the PLE peak energy does not change even though the detection energy is different, contrary to the case of the QD solution with size distribution where the PLE peak energy does change when the detection energy is different.
(3) I think that the above phenomenon is a clear evidence of electronic relaxation among QDs in the QD arrays. There may be two kinds of interpretation for this phenomenon: one is the electronic resonance transfer by the formation of minbands in the QDSLs and the other is the phonon-assisted rapid energy transfer toward those QDs with larger sizes, caused by the overlapping of electronic excited states among adjacent QDs.
(4) I imagine that the former interpretation might be more probable because you have observed the periodic structural order of the QD arrays by means of x-ray diffraction measurement. However, the diffraction pattern might appear even if there is only a partial regularity inside the QD arrays. In order to confirm the formation of minibands, it may be desirable to get further experimental evidence such that the miniband energy width and/or the bandedge energy depends on the superlattice constant (that is the distance between adjacent QDs), for example, by changing the length of the ligand.
(5) Anyway, I enjoyed reading the paper very much. I hope your further success in the near future.
... Reply (June 27):
Thank you for your informative comments on the manuscript. We really appreciate it. Currently, we are fabricating samples with varying ordered structure scales and investigating the relationship between ordered structure scales and miniband formation. Through this research, we are trying to elucidate the phenomena occurring in the ordered structure.

... Comment and Question-1(Takeshi Ohno, July 23)
It’s interesting you found that CdSe/ZnS PL QY achieved 70% regardless of temperature.
By the way, how much is the PL QY of CdSe itself without forming CdSE/ZnS core/shell ?
... Reply (August 17):
Thank you for your comment and question on the manuscript.
The PL QY of bare CdSe is 1.5 %.

M-09(Atsuo Matsui, Prof.)
...Question-1 (Masao Kamada, Prof. July 7):
Is there any reason why the author focuses on pancreas cancer?
... Reply(July 11):
Curing pancreatic cancer is a promising target for medical doctors because pancreatic cancer is technically very difficult to perform an operation and the rest of the client life is fairly short. We therefore do not set it for the first target but place it in our FINAL target.
Why we are interested in curing cancer? Please reffer M-09 description, where we looked back the history of condensed matter photophysics and learnt that photo-physics research trend arrives at medical treatment of cancer.

... Question-2 (Masao Kamada, Prof. July 7)
How can you protect normal tissues in the skin and other regions from RF?
... Reply (July 11):
Our reply would not match with Q2, because our proposed technique is planned to reduce RF (in questioner's word).

... Comment-1 (Shingo Saito, Dr. July 13):
Because the cell contains much of water, we can treat the absorbance of water to THz wave as that of cell for the beginning. Absorbance of water to THz radiation is strong and THz wave can not penetrate into the deep area. It is important the consideration of the irradiation of THz wave for the future application.
.... Reply(July 14):
We appreciate very much for your keen comment on water molecule which absorbs THz light. Applying THz light to kill cancer cells is advantageous because (1) cancer cell includes lots of water molecules and (2) cancer cell is weak against heat. Please visit a diagram illustrated on page 30 in abstract-booklet, where you will learn how cancer cells are killed effectively by heat. On the other hand, as you suggested THz light is absorbed by water molecules on the light path and warms up water molecules on its path, which results in killing normal cells. Killing normal cells is however not too much as far as the THz light beam is squeezed down to make aperture small. We mean that the area (special extent), which is warmed up by THz light can be minimized. Please look at an illustration on Page 31, in which RF (1KHz~1 THz) wave hits human body over a wide range. Applying THZ light for cancer operation is therefore much favorable than to apply AF wave. The strong absorption of THz light by water is very effective to kill cancer cells located at the surface of the organ. However, due to strong absorption of THz light by water molecules the light does not come into deep in the organ where cancer cells are located. We have to develope a technique to bring THz light into deep inside human body.

M-10 (Piotr Petelenz, Prof.)
... Question-1(Ken-ichi Mizuno, Prof. July 15):
I’m not familiar with the names of two molecules, oligothiophene and sexithiophene. Could you demonstrate the constitutional structures of both molecules, together with their crystal structures?
... Reply: (August 3)
The names are decreed by the normal rules of chemical terminology. “Sexi” (from Latin) means “six”, and refers to the number of constituent thiophene rings that form this molecule. The standard in organic chemistry was to use in similar contexts Greek numerals (it would be “hexa” in this case), but the first authors intended to make the name somewhat frivilous. “Oligo” means “a few” (in contrast to “poly”, meaning “many”, which applies to polymers). To date, I have come across papers on bi-, ter-, quater-, quinque-, sexi-, septi-, octi- thiophene which consist of 2 to 8 thiophene rings. These are all oligothiophenes. There is (to my knowledge) no precise limit on the number that can be called “a few” (“several”). Septithiophene and octithiophene (7 and 8 rings, respectively) probably also count as oligothiophenes; although I would be rather hesitatant to use the term in these cases. For example, the structural formula for 6T (sexithiophene) is

Exemplary crystal structures are available in S. Möller, G. Weiser, F. Garnier, Phys. Rev. B 61, 15 749 (2000), P. Hermet, J.-L. Bantignies, A. Rahmani, J.-L. Sauvajol, M. R. Johnson, J. Phys. Chem. A 2005, 109, 4202-4207

... Comment-1 (Ken-ichi Mizuno, Prof. July 15)
Your abbreviations, UV/Vis, will not be understood by young graduate students, especially “Vis” is not popular among photo-physics researchers.
... Reply (August 3):
Many thanks for the comment. I apologize for using the abbreviation that among the spectroscopists known to me is standard. It stands for ultraviolet/visible.

... Question-2 (Ken-ichi Mizuno, Prof. July 15)
It is hard for me to figure out molecular arrangement in twin crystal, that is, the meaning of the word “twinning“ is not clear to me.
... Reply (August 6): “Crystal twinning” is a standard term in crystallography and geology. The definition is cited below: Crystal twinning occurs when two separate crystals share some of the same crystal lattice points in a symmetrical manner. The result is an intergrowth of two separate crystals in a variety of specific configurations. The surface along which the lattice points are shared in twinned crystals is called a composition surface or twin plane. The above is cited from: https://en.wikipedia.org/wiki/Crystal_twinning (3 Aug 2020), where examples are also presented.
A twin crystal may be viewed as a specific case of a crystal pair, fused in high-symmetry configuration. On microscopic scale, in junction regions the lattice may be locally distorted, i.e. some molecules (or other crystal basis, depending on the kind of the crystal) may be somewhat displaced with respect to their normal positions, or some may be missing (like in the dislocation case).
[Cf. https://en.wikipedia.org/wiki/Dislocation (3 Aug 2020)].
In molecular crystals, the crystal structure is determined by the weak Van der Waals forces. In effect, the energy gaps between different local geometries are small, so that a narrow energy interval may encompass many local energy minima corresponding to a variety of different local configurations. For this reason, disordered phases often emerge, and it is usually difficult to grow large single crystals of this kind. It is quite common that in macroscopic samples the ordered crystallites are separated by disordered regions.
Our model is an idealized image of two fused macroscopic crystals, symmetry-related or not, that may either share some composition surface or be connected by a disordered layer which is sandwiched between them, and is sufficiently thin to make its contribution negligible for a macro-scale spectroscopic measurement. Thus, the structure of the junction region is irrelevant for our argumentation.
...Question-3(Ken-ichi Mizuno, Prof. August 10):
How to distinguish “Twin” crystals?With naked eyes, or by using special tools, or by specific techniques?

M-11 (Ayane Murano, M2)
...Question-1: (Masao Kamada, Prof. July 7):
Please let me know the detailed explanation of N 1s XPS spectra. What is origin of the shoulder at 396 eV?
...Reply (July 17):
Thank you for your questions on my manuscript. I will answer your questions. The presence of the main peak and shoulder implies the presence of two types of nitrogen. The binding energy of the main peak corresponds to that of 6-coordinated bulk nitrogen in TiN. It is thought that the origin of the shoulder is nitrogen bound to the titanium on the surface of oxidized powder [1] or nitrogen substituted for oxygen in TiO2 [2]. In both cases, such nitrogen has a low coordination number than that in TiN. Due to the sputtering procedure, the surface structure was uniformly changed to be observed a single band. [1] C. M. Zgrabik, and E. L. Hu, Opt. Mater. Express 5 (2015) 2786.

... Question-2: (Masao Kamada, Prof. July 7)
The intensity of N 1s XPS spectra decreases at high temperatures. Does this indicate the desorption of nitrogen atoms during the heat treatment?
...Reply(July 17):
Yes. With increase in heating temperature, the oxidation with desorption of nitrogen proceeds from the surface of the powder particle. The fraction of nitrogen is considerably small in observable range of XPS measurement. However, diffuse reflectance and XANES spectra indicate that nitrogen still remains in the particle enough to observe.

M-12 (Yoichiro Mushiaki, M2)
... Suggestion-1(Yoshitaka Oeda, Dr. July 25):
Your paper is well organized.
If you show the structure of YIG, it will be much easier for us to understand your paper .
... Reply: (July 30)
Thanks for your suggestion. The whole crystal structure of YIG, which is categorized as a garnet-type structure (space group la3d), is cubic, but the local structure is very complicated. The figure of YIG structre may not necessarily be instructive to understand our paper. It would be great if you refer to the figure in the related article below.

What is the material of each lens?
... Reply:(July 27)
The material of the lenses is BK7 glass. Laser pulses go through the lenses, but the THz wave does not go through any of the three lenses.

... Question-2( Keiichiro Nasu, Prof. Aug 8)

M-18 (Richard J. Cogdell, Prof.)
... Question-1 (Yoshitaka Oeda, Dr. May 20):
Your manuscript is very interesting. Unfortunately, however, I do not understand a word "refix" in your manuscript.
... Reply (May 21):
Refix means to reabsorb. Carbon dioxide was originally removed from the atmosphere by photosynthetic activity and then put back into the air by burning fossile fuels.

... Questions (Yoshitaka Oeda, Dr. July 7):
My understanding on your manuscript M-18 is described below.Is my understanding perfect?
The amount of carbon dioxide on the earth is reduced by photosynthesis (dark reaction) which fixes carbon dioxide to carbohydrates. The energy conversion efficiency from sunlight energy into photosynthesis (light reaction) of plants is small less than 1%. . Besides, the efficiency of dark reaction is poor. Contrary to the energy conversion in planets, in solar cells the energy conversion efficiency is about 20%, which may supply much energy to plants for photosynthesis (dark reaction). This suggests that solar cells can fix more carbon dioxide into carbohydrates effectively.
Asuming my understanding is perfect, I have a few questions.
... Question-2 (Yoshitaka Oeda, Dr. July 7)
How is the electric energy obtained from the solar cell supplied to the photosynthesis (dark reaction) cycle?
... Question-3 (Yoshitaka Oeda, Dr. July 7)
Even if the energy conversion efficiency is increased by the solar cell, I think the generated amount of carbon dioxide does not increase if the efficiency of photosynthesis (dark reaction) is the same. How is it?
.... Reply to Question-2, and 3 (July 13):
The energy harvested by the solar cell would be used to power carbon dioxide fixation. However, the idea the idea would be to not use a photosynthetic organism directly but to engineer, probably, a bacterium that can derive its energy from electricity (such as Geobacter) to use carbon dioxide to make medium chain hydrocarbon products, such as farnesene. In this way you gain the benefit of high efficiency and tailor the product to one you desire.

... Question-4 (Yoshitaka Oeda, Dr. July 7)
Does the carbohydrate conversion efficiency by photosynthesis (dark reaction) vary greatly depending on the type of plant?
.... Reply (July 13):
Yes, some plants can be more efficient. So far, the best are algae. But you have to distinguish between actual operating efficiency and the theoretical maximum efficiency. There is usually a big gap between the two!

... Question-5 (Yoshitaka Oeda, Dr. July 7)
As a method of converting carbon dioxide to carbohydrates, what is the advantage of photosynthesis (dark reaction) compared to the other inorganic methods?
.... Reply (July 13):
So far, inorganic methods do not work at atmospheric concentrations of carbon dioxide. They only work at high carbon dioxide concentrations and usually high temperature too. Photosynthesis is the only major process that can work at 0.04% carbon dioxide concentrations.

M-20 ( Juergen Koehler, Prof.)

We are very sorry but we have to announce that Prize Nomination Committee have missed to find a graduate student participant who satisfies their criteria for Excellent Presentation Prize.

Scope: This conference has been planned to discuss topics across all fields of Condensed Matter Photo-Physics. To promote our research activities further we should bring in young researchers with wide-ranging views and pioneering spirits. Looking back at the history of condensed matter photo-physics over the past 100 years, new concepts and ideas were often triggered by people working on the outskirts of traditional research realms. Therefore, we wish to take in fresh blood.

Owing to COVID-19 pandemic, iCAMP’20 will be held under a novel design; iCAMP’20 in summer does not include any meeting where participants get together, that is, we will not have oral and poster sessions there.

Nevertheless, we will keep our policy to encourage young participants to present their papers in good shape to distribute their new results. This new presentation style will probably press young participants to enforce additional effort to polish their manuscripts. We hope they overcome this severe barrier and obtain higher educational capacity.
