Amano-Koide Collaborative Research Lab
This collaborative research laboratory was established in Nagoya Univ. and NIMS and is managed by Prof. Hiroshi Amano and Dr. Yasuo Koide, NIMS Director/former Executive Vice President, as a mutual cross-appointment. It facilitates crystallographic, electrical, and optical property characterization and the development of new measurement techniques for developing GaN-based power devices. The research will be effectively promoted by using advanced measurement and analysis equipment and techniques in NIMS.

TOYODA-GOSEI GaN Leading Innovative R&D Industry-Academia Collaborative Chair
In 1986, Toyoda Gosei Co., Ltd., started a joint research project with Professor Akasaki, Professor Amano, and Toyota Central R&D Labs., Inc., and began fundamental research on GaN materials. The commercialization of LEDs and their subsequent widespread adoption were based on this research. The core competencies cultivated from research, commercialization, expansion, and continuation will be utilized to create new business opportunities.
