Expertise : Physics of defects/imperfections in various
semiconductors and their reactions for applications;
Crystal growth of semiconductors
We are engaged to establish basic knowledge of crystal defects on an atomic scale in semiconductors. For the purpose, we are characterizing various properties of defects, i.e. atomic and electronic structures, nucleation and dynamic modifications as well as mutual reactions/ complex formation in semiconductors as Si, SiGe, Ge, SiC, GaN, ZnO, SiC, and so forth by using multi-techniques in a wide scale range and multi-dimension. The research is extended to control of defect states for advanced materials with ultimate functions as "Defect Science".
