A half-step in quantized conductance for low-density electrons in a quantum wire
Godfrey Gumbs, Antonios Balassis, Danhong Huang +2
We investigated the effect due to perpendicular magnetic field on quantum wires where spin-orbit interaction (SOI) of electrons is not neglected. Based on the calculated energy dis…

Optical Modulation Effects on Nonlinear Electron Transport in Graphene in Terahertz Frequency Range
Danhong Huang, Godfrey Gumbs, O. Roslyak
We describe very fast electron dynamics for a graphene nanoribbon driven by a control electromagnetic field in the terahertz regime. The mobility as a function of bias possesses a…

Field enhanced electron mobility by nonlinear phonon scattering of Dirac electrons in semiconducting graphene nanoribbons
Danhong Huang, Godfrey Gumbs, O. Roslyak
The calculated electron mobility for a graphene nanoribbon as a function of applied electric field has been found to have a large threshold field for entering a nonlinear transport…
