Strong Effects of Interlayer Interaction on Valence-Band Splitting in Transition Metal Dichalcogenides
Garrett Benson, Viviane Zurdo Costa, Neal Border +10
Understanding the origin of valence band maxima (VBM) splitting in transition metal dichalcogenides (TMDs) is important because it governs the unique spin and valley physics in mon…
Coulomb drag in metal monochalcogenides double-layer structures with Mexican-hat band dispersions
S. Rostami, T. Vazifehshenas, T. Salavati-fard
We theoretically study the Coulomb drag resistivity and plasmon modes behavior for a system composed of two parallel p-type doped GaS monolayers with Mexican-hat valence energy ban…
Collective plasmonic excitations in double-layer silicene at finite temperature
N. Dadkhah, T. Vazifehshenas, M. Farmanbar +1
We explore the temperature-dependent plasmonic modes of an n-doped double-layer silicene system which is composed of two spatially separated single layers of silicene with a distan…
Plasmon-phonon coupling in a valley-spin-polarized two-dimensional electron system: a theoretical study on monolayer silicene
M. Mirzaei, T. Vazifehshenas, T. Salavati-fard +2
We study the hybrid excitations due to the coupling between surface optical phonons of a polar insulator substrate and plasmons in the valley-spin-polarized metal phase of silicene…
Phononic thermal conductivity in silicene: the role of vacancy defects and boundary scattering
M. Barati, T. Vazifehshenas, T. Salavati-fard +1
We calculate the thermal conductivity of free-standing silicene using the phonon Boltzmann transport equation within the relaxation time approximation. In this calculation, we inve…
