Theoretical and Applied Physics

Takashi Matsuoka is a Professor at the Institute for Materials Research, Tohoku University. He has published more than 100 papers in journals and more than 50 patents including U.S. and EPC patents. In 1980s, he developed the laser diode used for the present optical communications systems. He has also developed nitride semiconductors. He proposed the material concept for blue LEDs and showed how to grow InGaN as an emitting layer. He was the Editor of Applied Physics Express for five years. He is a member of IEEE, MRS, ACerS, SPIE, and several other societies in Japan.
