Plasmons in single- and double-component helical liquids: Application to two-dimensional topological insulators
O. Roslyak, Godfrey Gumbs, D. H. Huang
The plasmon excitations in proposed single- and double-component helical liquid (HL) models are investigated within the random-phase approximation, by calculating the density-densi…
Spectroscopic Characterization of Gapped Graphene in the Presence of Circularly Polarized Light
Godfrey Gumbs, O. Roslyak, Danhong Huang +1
We present a description of the energy loss of a charged particle moving parallel to a graphene layer and graphene double layers. Specifically, we compare the stopping power of the…
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…
