Diamond into the ultimate optical and electronic semiconductor material
We are conducting research on high-quality growth of diamond thin films and their device applications. Among wide-gap semiconductors, diamond has a particularly large bandgap and is expected to be a next-generation semiconductor. Compared to other wide-gap materials such as SiC and GaN, there are many unexplained phenomena regarding the high-quality synthesis of diamond crystals and the physical properties of diamond. is essential.
