○Development of Technology for III Nitride Semiconductors and Power Devices

Improving energy efficiency of consumer electronics is effective in reducing CO2 emissions. III nitride semiconductors and their power devices are fascinating as key technologies that enable high efficiency and downsizing of AC/DC, DC/DC converters, etc. which are used in these electronic devices. AlGaN/GaN HEMTs with two-dimensional electron gases (2DEG) have the characteristic of high-speed switching and are especially effective in miniaturizing devices. We are working on research projects on excellent GaN crystal growth, new-structure devices with new mechanisms, demonstration tests of our prototype devices and so on.

○Development of Optical Device Technology

For further widespread applications of nitride-semiconductor optical devices, it is important to extend the device wavelength to the red near infrared and the ultraviolet spectral range and to add novel functionalities to conventional devices. In GaN-OIL, we will focus on the realization of highly directional LEDs in the whole visible spectral range based on a unique directionality control technique and the development of crystal growth techniques of In-rich InGaN by means of a MOCVD system equipped with a quasi atmospheric pressure plasma source. We will also focus on the development of advanced packing technologies of micro LEDs towards the application of directional LEDs to low power consumption displays for wearable electronics and harsh-environment optical communication systems.
