Developing a semiclassical Wentzel-Kramers-Brillouin theory for model
Kathy Blaise, Chinedu Ejiogu, Andrii Iurov +3
We have developed a complete semiclassical Wentzel-Kramers-Brillouin (WKB) theory for model which describes a wide class of existing pseudospin-1 Dirac cone mater…
Generalized Peierls substitution for the tight-binding model of twisted multilayer graphene in a magnetic field
Thi-Nga Do, Po-Hsin Shih, Hsin Lin +3
We propose a generalized Peierls substitution method in conjunction with the tight-binding model to explore the magnetic quantization and quantum Hall effect in twisted multilayer…
Engineering plasmon modes and their loss in armchair graphene nanoribbons by selected edge-extended defects
Thi-Nga Do, Po-Hsin Shih, Godfrey Gumbs +1
The effect of edge modification of armchair graphene nanoribbons (AGNRs) on the collective excitations are theoretically investigated. The tight-binding method is employed in conju…
Coherent-scatterer enhancement and Klein-tunneling suppression by potential barriers in gapped graphene with chirality-time-reversal symmetry
Farhana Anwar, Andrii Iurov, Danhong Huang +2
We have utilized the finite-difference approach to explore electron-tunneling properties in gapped graphene through various electrostatic-potential barriers changing from Gaussian…
Defect capturing and charging dynamics and their effects on magneto-transport of electrons in quantum wells
Andrii Iurov, Danhong Huang, Godfrey Gumbs +2
The defect corrections to polarization and dielectric functions of Bloch electrons in quantum wells are first calculated. Following this, we derive the first two moment equations f…
Influence of electric and magnetic fields and -edge bands on the electronic and optical spectra of graphene nanoribbons
Thi-Nga Do, Po-Hsin Shih, Godfrey Gumbs +1
The unusual electronic and optical properties of armchair and zigzag graphene nanoribbons (GNRs) subject to in-plane transverse electric and perpendicular magnetic fields have been…
