Spectra-Physics Prize goes to Prof. Kazunari Matsuda, Kyoto University. Congratulations!

Kazunari Matsuda graduated from Nagoya University in 1993. He obtained his doctorate in 1998 on the femtosecond time-resolved spectroscopy of strongly-correlated electron system and then joined to Kanagawa Academy of Science and Technology. He moved to Kyoto University in 2004 and was promoted to full professor in 2010.

Selection Committee Chairman’s report

We have made a close examination of each nominee’s research achievements. Kazunari Matsuda is the most outstanding exciton researcher who achieved original and novel research results with pioneering features.

Merit of the Prize Winner’s Research Achievement

Development of science is often triggered by new experimental equipment or new instrumental technique. Kazunari Matsuda was engaged in developing a high-resolution near field optical microscope at Kanagawa Academy of Science and Technology. This microscope enabled him to monitor a luminous spot as small as 30-nm in size. Making full use of this equipment he monitored in 2003 the spatial spread of exciton wave-function in a GaAs quantum dot. After he moved to Kyoto University, he extended his study to excitons and trions in low-dimensional materials such as carbon nanotube, graphene, and monolayer transition metal di-chalcogenides. He has thus succeeded to reveal the excitonic properties in extremely thin materials. In performing these novel works, the techniques and the know-how that he had learnt by experience during his early days served effectively. Some of his outstanding recent achievements are given below.

(1) Observation of mesoscopic quantum phenomena (Aharonov-Bohm effect) of a single exciton state (Phys. Rev. Lett. 101, 147404 (2008)).

(2) Discovery of positive and negative charged excitons (trions) at room temperature in carbon nanotubes (Phys. Rev. Lett. 106, 037404 (2011):Physics Viewpoint; Physics 4, 5 (2011), J. Am. Chem. Soc. 134, 14461 (2012)), which is the first observation of room temperature-stable trion (charged exciton). This finding leads to the realization of quantum manipulation in carbon based materials.

(3) Realization of drastic improvement of photoluminescence quantum efficiency using hybrid nanostructure and novel optical application of carbon nanotubes (Nature Photonics 7, 715 (2013), Nature Commun. 6, 6305 (2015), Nature Commun. 6, 8920 (2015)).

(4) Giant optical absorption at the exciton resonance and the chemical control of exciton and charged exciton in monolayer transition metal dichalcogenides (Nano Lett. 13, 5944 (2013). Nature Commun. 5, 4543 (2014)).

Contribution to EXCON

Local Organization Committee for EXCON’08 (Kyoto, Japan)

Local Organization Committee for EXCON’18 (Nara, Japan)

Because of his excellent achievements he has been frequently (ca. 130 times) requested to give invited talks at domestic and international conferences which include EXCON’04 (Cracow, Poland) and EXCON’15 (Montréal, Canada). His research achievements certainly encourage young exciton researchers and stimulate trained researchers as well. To sum up, Kazunari Matsuda’s novel works are evaluated to be pioneering and meet the requisites of Spectra-Physics Prize which will be awarded at EXCON’18.


Invitation to Nominate Candidates for Spectra-Physics Prize

We, ICC (International Consultative Committee of Exciton Research) are pleased to announce that Spectra-Physics Prize is now being established to honor an outstanding exciton researcher who achieved original and novel experimental research results with pioneering features. Theoretical works which have contributed to yield unprecedented exciton research field with evidence of many experimental reports are not excluded. The nominee should be around 35-55 years old. The prize consists of JPY 200,000 and a certificate which will be awarded at the prize ceremony to be held during the EXCON’18 Conference at Nara. This will be preceded by presentation of the merits of the laureate’s achievement by the ICC Chairman (Atsuo Matsui), and followed by an invited talk given by the laureate. We invite all members of the exciton-research community who receive ICC Report by email to recommend candidates for the Prize. The format of the recommendation is left to the discretion of the recommending person, but the pertinent letter should clearly specify the outstanding features of the nominee’s achievement, and should necessarily include the recommending person’s affiliation and his/her status (Professor, Dr, etc.). Self-recommendations will not be accepted. The recommendation letter should be sent to ICC Office or to ICC Representative Europe by email before January 1, 2018.
