Biography

Yasuyuki Kobayashi was born in Tochigi on August 9, 1962. He received the B.S. degree in electronics engineering from the University of Utsunomiya, M.S. degree in electronics engineering from the University of Shizuoka, and Ph.D. degree in Material engineering from the Tokyo University of Agriculture and Technology in 1986, 1988, and 1996, respectively. He joined NTT Communication Exchange System Laboratories in 1988 and belonged to NTT Basic Research Laboratories in 1991. In 2000, He went to University of Stuttgart, as a visiting researcher. I spent a year on working with Professor M. Pilkun, Dr. F. Scholz. I investigated self-assembled quantum island of GaInN/GaN on Sic by metalorganic vapor phase epitaxy. After returning to NTT Basic Research Laboratories, I have been engaged in research on MOVPE growth of group-III nitride systems as a senior research scientist, supervisor.


Research Interests

Since 1991 he has engaged in the study of in-situ control of strained InAs/InP heterostructure growth, the growth of atomic-layer structure, and in-situ optical monitoring of the surface during MOVPE growth using surface-photo-absorption (SPA) method. His current interest is high quality hexagonal boron ntirides (h-BN) heteroepitaxial growth. He is a member of the Japan Society of Applied Physics.
