獻慶簡單介紹一下最近的研究主題 標題: Spin-polarized magneto-electronic properties in buckled monolayer GaAs (單層皺褶砷化鎵的極化自旋磁電子性質) 作者群姓名: Hsien-Ching Chung, Chih-Wei Chiu, Ming-Fa Lin (鍾獻慶、邱志偉、林明發) 文章摘要: We develop the generalized tight-binding model to fully explore the magneto-electronic properties of monolayer GaAs, where the buckled structure, multi-orbital chemical bondings, spin-orbit coupling, electric field, and magnetic field are considered simultaneously. The diverse magnetic quantization covers three groups of spin-polarized Landau levels (LLs) near the Fermi level, with the unique initial energies, LL degeneracy, energy spacings, magnetic-field-dependence, and spin splitting. Furthermore, the Landau state probabilities exhibit specific oscillation patterns, being composed of the localization centers, node regularities, and energy-dependent variations of the dominating orbitals. The density of states directly reflects the main features of the LL energy spectra in the form,...
