Masterclass in Semiconductor Photonics
Abstract
This talk explains the cutting-edge technology of micro-LEDs. The development of monolithic RGB micro-LEDs is the bottle-neck technology for the new displays. Micro-LED displays will be useful for mobile phones and head-mount displays shortly. The new displays have lower light reflection and save energy. It means we can use such new mobile phones under the sunlight, and their batteries last several times more rather than current displays. Also, the new displays are thinner and lighter weight, so the head-mount ones will become like glasses.
Brief Biography
Kazuhiro Ohkawa is a professor at KAUST. He is the principal investigator of the Energy Conversion Devices and Material (ECO Devices) laboratory. Also, he is a Fellow of the Japan Society of Applied Physics. He received his Ph.D. degree from the University of Tokyo, Japan. He worked for Panasonic, University of Bremen as a lifelong honorary professor in Germany, and Tokyo University of Science. He also has the title of visiting professorship from Mie University, Japan, and Xiamen University, China.
His research interests are crystal growth and optoelectronics. He has developed a nitride MOVPE simulation. It becomes a useful technology for LED/LD and electronic device companies. He invented nitride photocatalysts that work as water splitting and artificial photosynthesis. His group developed a novel MOVPE for nitride semiconductors. This MOVPE technology made it possible to grow high-quality & high-In-content InGaN and resulting in red LEDs. Their recent paper about red LEDs won the outstanding paper award from JSAP in 2023.
