Effect of Rashba spin-orbit coupling on the electronic, thermodynamic, magnetic and transport properties of GaAs, InAs and InSb quantum dots with Gaussian confinement

Abstract

The effect of Rashba spin orbit interaction on the electronic, thermodynamic, magnetic and transport properties of a one-electron Gaussian quantum dot is investigated in the presence of a magnetic field and its interaction with the electron spin using the canonical ensemble approach. The temperature-dependent energy, magnetization, susceptibility, specific heat and the persistent current are calculated as a function of the spin orbit coupling parameter. The results are applied to GaAs, InAs and InSb quantum dots. (C) 2016 Published by Elsevier B.V.
