Abstract

The effects of magnetic field, temperature, potential parameters and impurity on the magnetic and thermodynamic properties of GaAs quantum dot confined by the parabolic-inverse square plus Gaussian potential are investigated. The Hamiltonian of the system is solved within the effective-mass approach and energy levels are obtained. The results show that temperature, magnetic field, potential parameters and impurity have a great influence on the magnetic and thermodynamic properties of the structure.
