This laboratory is engaged to establish fundamental knowledge of crystal defects / local distortions on an atomistic scale in semiconducting materials. For this purpose, we are characterizing various basic properties of defects, i. e., atomistic and electronic structures, nucleation processes and dynamic modifications as well as mutual reactions / complex formations in a wide variety of semiconductors as Si, Ge, SiC, (In, Al, Ga)N, ZnO, and so forth. The research is extended to control states of defects for advanced and ultimate functions of materials as Defect Science.
