Tunneling conductivity fast modulated by optically-dressed electrons in graphene and a dice lattice
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +2
Based on the transmission coefficient of tunneling electrons, we have presented tunneling current and conductivity across a square-potential barrier for both graphene and -$\mat…
Adjustable propagating plasmons in lattice-based armchair nanoribbons
Andrii Iurov, Liubov Zhemchuzhna, Paula Fekete +5
We have obtained and analyzed the electronic states, polarization function and the plasmon excitations for -based nanoribbons with armchair termination. The calcu…
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…
Generalized WKB theory for electron tunneling in gapped lattices
Nicholas Weekes, Andrii Iurov, Liubov Zhemchuzhna +2
We generalize Wentzel-Kramers-Brillouin (WKB) semi-classical equations for pseudospin-1 materials with arbitrary hopping parameter , which includes the…
