The Magnetization of Single GaAs Quantum Dot with Gaussian Confinement

Abstract

The Magnetization of single electron confined in a quantum dot presented in a magnetic field had been calculated by solving the Hamiltonian including the spin using exact diagonalization method. We had investigated the dependence of the magnetization on temperature, magnetic field and confining potential. The energy of the electron had been displayed as function of magnetic field, Gaussian confinement potential height and quantum dot size. The comparisons show that our results are in very good agreement with reported works.
