First-principles study of the superconductivity in MgB2 bulk and in its bilayer thin film based on electron–phonon coupling
dispersion, isotropic Eliashberg function α2F(ω), and electron–phonon coupling have been calculated within the framework of density functional theory (DFT). Our results indicate that holes at the top of boron σ bands mainly and holes in the boron π band...
A study of Inelatic Electron-Polar optical phonon Scattering in CdTe
The dipolar electric field arising from the opposite displacement of the negatively and positively charged atoms provides a coupling between the electrons and the lattice which results in electron scattering.
The role of electron–phonon interaction on the transport properties of graphene based nano-devices
Transport through a nano-device in the presence of electron–phonon interaction has been studied by using unitary-transformation scheme together with the non-equilibrium Green׳s function formalism. The non-interacting Hamiltonian is written within...
A study of inelastic electron–phonon interactions on tunneling magnetoresistance of a nano-scale device
In this research, we have studied the effect of inelastic electron–phonon interactions on current–voltage
characteristic and tunneling magnetoresistance of a polythiophene molecule that is sandwiched between
two cobalt electrodes using...
Electron Mobility Calculation in GaAs and the Effects of Fast Neutron Radiation on its Crystal Structure
An iteration method has been developed for the study of electron transport properties in GaAs taking into account the different scattering effects. It is shown that electron-phonon scattering affects substantially the electron energy distribution...
