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…
Plasmon modes in monolayer and double-layer black phosphorus under applied uniaxial strain
S. Saberi-Pouya, T. Vazifehshenas, M. Saleh +2
We study the effects of an applied in-plane uniaxial strain on the plasmon dispersions of monolayer, bilayer and double-layer phosphorene structures in the long-wavelength limit wi…
Anisotropic hybrid excitation modes in monolayer and double-layer phosphorene on polar substrates
S. Saberi-Pouya, T. Vazifehshenas, T. Salavati-fard +1
We investigate the anisotropic hybrid plasmon-SO phonon dispersion relations in monolayer and double-layer phosphorene systems located on the polar substrates, such as SiO2, h-BN a…
Strong anisotropic optical conductivity in two dimensional puckered structures: The role of Rashba effect
S. Saberi-Pouya, T. Vazifehshenas, T. Salavati-fard +2
We calculate the optical conductivity of an anisotropic two-dimensional system with Rashba spin-flip excitation within the Kubo formalism. We show that the anisotropic Rashba effec…
