Anomalous magneto-transport properties of bilayer phosphorene
Jhao-Ying Wu, Wu-Pei Su, Godfrey Gumbs
The magneto-transport properties of phosphorene are investigated by employing the generalized tight-binding model to calculate the energy bands. For bilayer phosphorene, a composit…
Diversified properties of carbon substitutions in silicene
Hai-Duong Pham, Shih-Yang Lin, Godfrey Gumbs +2
The theoretical framework, which is built from the first-principles results, is successfully developed for investigating emergent two-dimensional (2D) materials, as it is clearly i…
Nonlinear transport of ballistic Dirac electrons tunneling through a tunable potential barrier in graphene
Farhana Anwar, Andrii Iurov, Danhong Huang +2
Dirac-electronic tunneling and nonlinear transport properties with both finite and zero energy bandgap are investigated for graphene with a tilted potential barrier under a bias. F…
Valley- and spin-dependent quantum Hall states in bilayer silicene
Thi-Nga Do, Godfrey Gumbs, Po-Hsin Shih +2
The Hall conductivity of many condensed matter systems presents a step structure when a uniform perpendicular magnetic field is applied. We report the quantum Hall effect…
Magneto-transport properties of doped graphene
Po-Hsin Shih, Thi-Nga Do, Godfrey Gumbs +2
The effect due to doping by B, Si, N on the magneto-transport properties of graphene is investigated using the generalized tight-binding model in conjunction with the Kubo formula.…
Diverse quantization phenomena in AA bilayer silicene
Po-Hsin Shih, Thi-Nga Do, Godfrey Gumbs +3
The rich magneto-electronic properties of AA-bottom-top (bt) bilayer silicene are investigated using a generalized tight-binding model. The electronic structure exhibits two pairs…
