Tunneling conductance of graphene ferromagnet-insulator-superconductor junctions
Ya-Fen Hsu, Guang-Yu Guo
We study the transport properties of a graphene ferromagnet-insulator superconductor (FIS) junction within the Blonder-Tinkham-Klapwijk formalism by solving spin-polarized Dirac-Bo…
Transverse force generated by an electric field and transverse charge imbalance in spin-orbit coupled systems
Tsung-Wei Chen, Hsiu-Chuan Hsu, Guang-Yu Guo
We use linear response theory to study the transverse force generated by an external electric field and hence possible charge Hall effect in spin-orbit coupled systems. In addition…
Tuning linear and nonlinear optical properties of wurtzite GaN by c-axial stress
Duanjun Cai, Guang-Yu Guo
We study the linear and nonlinear optical properties of wurtzite GaN under c-axial stress field, using density functional theory calculations. The fully structural optimization at…
Microscopic origin of light emission in Al_yGa_{1-y}N/GaN superlattice: Band profile and active site
Duanjun Cai, Junyong Kang, Guang-Yu Guo
We present first-principles calculations of AlGaN/GaN superlattice, clarifying the microscopic origin of the light emission and revealing the effect of local polarization within th…
