报告摘要:

Itis known that defects or dopants can fundamentally determine the overallelectronic structures of semiconductors. In this talk, I will give anintroduction on our recent works in this field: under equilibrium conditions,we have developed a unified theory to understand the strain-dependent defectsolution, defect levels, and Fermi energy pinning effects, and we also showthat new spin-orbital coupling effects may be hidden in the harmful deep-leveldefects; under nonequilibrium conditions, we have developed theories tounderstand the formation of complex defects in the surface or interface ofsemiconductors, and we have developed a unified formula to understand theplasmonic excitation and proposed a new transport model to realize ideal chargetransport in ferroelectric superlattices; under extreme-nonequilibriumconditions, we are developing methods to calculate the time-dependent defectformation and evolution in semiconductors and their effects on the fundamentalelectronic structures of semiconductors.
