Abstract
The Rashba and Dresselhaus spin-orbit interactions and magnetic field effect on an off-center neutrally charged hydrogenic donor impurity D0 in a three-dimensional (3D) GaAs Gaussian quantum dot is investigated in the framework of effective-mass approximation theory. By performing a unitary transformation the effect of the spin-orbit interactions (αR,αD) The Rayleigh-Ritz variational method is employed for the resulting Hamiltonian with a simple wave function to determine the ground state (GS) energy, GS magnetic moment, and GS magnetic susceptibility of an off-centre hydrogenic donor impurity. The results show that the Rashba spin-orbit interaction reduces, the Dresselhaus spin-orbit interaction and magnetic field enhances the total GS energy of the donor impurity. © 2020 Author(s).
