Researchers Develop ß-Gallium Oxide Thick Films for Next Generation Power Electronic Devices

Professor Yoshinao Kumagai and Assistant Professor Ken Goto of Division of Applied Chemistry, Institute of Engineering, Tokyo University of Agriculture and Technology (President: Kazuhiro Chiba) and Assistant Professor Shogo Sasaki of the University's FLOuRISH Institute, in collaboration with Mr. Junya Yoshinaga, Mr. Guanxi Piao, and Dr. Kazutada Ikenaga of CSE Department, Innovation Unit, Taiyo Nippon Sanso Corporation (President: Kenji Nagata), and Dr. Yuzaburo Ban, Fellow of Taiyo Nippon Sanso CSE. (President: Takashi Aida), have achieved the high-speed growth of high-purity β-gallium oxide (β-Ga2O3) thick films using the metal-organic vapor phase epitaxy (MOVPE) method, which has been considered difficult.

β-Ga2O3 is attracting attention as an important semiconductor for next-generation power devices, which are essential for increasing the efficiency of power control and conversion systems. This achievement is expected to lead to the practical application of mass production technology for β-Ga2O3 power devices for the realization of an energy-saving society in the future.
