报告内容:

It is known that the intrinsic defects and extrinsic dopants determine the overall electronic, optoelectronic and magnetic properties of all the semiconductors. Although defect physics is an old topic in the material physics, we have recently made some new contributions in this field: 1. We have developed new ideas to effectively realize shallow n-type or p-type doping in wide-gap semiconductors, which may give rise to the best performances of transparent conducting materials until now; 2. We have developed new concepts to overcome the structure or electronic structure instabilities of dopants in zero-gap graphene or wide-gap BN, respectively; 3. We have demonstrated the conventional and unconventional alloy engineering to effectively control the defect levels in semiconductors, in order to suppress the deep-levels in semiconductors; 4, We have discovered some defect or doping induced new physics, e.g., greatly enhanced Tc in magnetic materials, new forms of spin-orbital coupling effects, and doping-independent THz plasmons.
