Teacher introduction

Professor Masaaki KUSUHARA

Masaaki KUSUHARA Masaaki Kuzuhara was born in Osaka, Japan, on November 5, 1955. He received the B.S., M.S., and Ph.D. degrees in electrical engineering from Kyoto University, Kyoto, Japan, in 1979, 1981, and 1991, respectively. In 1981, he joined NEC Corporation, Kawasaki, Japan, where he worked on the development of GaAs-based integrated circuits. From 1987 to 1988, he spent an academic year at the University of Illinois at Urbana-Champaign, IL, USA. From 2004 to 2020, he was a Professor at the Department of Electrical and Electronics Engineering, University of Fukui, Fukui, Japan. From 2020, he has been a Professor at the Department of Nanotechnology for Sustainable Energy in Kwansei Gakuin University, Hyogo, Japan. His research interests include physics and characterization of GaN-based heterojunction devices. He was awarded the 2002 Ichimura Prize from the New Technology Development Foundation. He is a Fellow of IEEE and Japan Society of Applied Physics.

Electron Devices

Our laboratory aims to promote innovative research on design, fabrication, and characterization of GaN-based electron devices. Nitride semiconductors are attracting attention as a material for low-loss power switching devices, as well as for microwave power devices in next-generation 5G/6G mobile and wireless communications.

Research in details

Electrical energy supplied from power stations is consumed in various forms and sizes by the electric appliances such as air conditioners and information devices such as personal computers around us. This process is called “Power Conversion”. In this process, a lot of electrical energy is wasted as heat. Therefore, we need to develop electron devices using new semiconductors with low power consumption capability during power conversion. In our laboratory, we promote research on electron devices using “Nitride Semiconductors”, which are suitable for low-loss, high-voltage, and high-frequency operation. Through characterization and simulation of the operation of fabricated devices, we will contribute to the realization of an energy-saving society and a next-generation mobile wireless communication system.
