Research Interest
My research primarily focuses on the crystal growth and process optimization of high-performance semiconductor materials for advanced device applications. This includes ultra-high-purity germanium (HPGe) crystals for radiation detectors, SiGe single crystals for quantum computing, wide-bandgap nitride semiconductors such as AlN for deep-UV and high-power devices, and III-V compound semiconductors like GaAs and InP for optoelectronics.
