Photonic devices using compound semiconductor

Overview

Sophisticated semiconductor crystal growth techniques are indispensable for development of many kinds of electronic and photonic devices. In Kondo Laboratory, we are studying fundamental properties of compound semiconductors and novel crystal growth techniques in order to realize innovative photonic devices. We are studying two kinds of material groups. First one is metal-halide perovskite semiconductors. They are promising materials for photonic applications such as solar cells and light emitting devices. Second one is Ⅲ-Ⅴcompound semiconductors such as GaAs. We have been working on wavelength-conversion devices, which can change color of laser, utilizing these materials. We are now studying fundamental properties of these materials and novel crystal growth and composition/conduction control techniques of metal-halide perovskite semiconductors in order to realize innovative photonic devices.
