ABSTRACT

In this paper, we investigated the average energy, specific heat, entropy and magnetic susceptibility of the cylindrical DMS quantum dot with respect to a change in magnetic field. The corresponding Schrodinger equation of a quantum dot was solved within the effective mass approximation. The resulting energy spectrum was used to find the corresponding expression for the average energy, specific heat, entropy and magnetic susceptibility. Then, the graphs of the average energy, specific heat, entropy and magnetic susceptibility as a function of the magnetic field were constructed. According to the results obtained, the average energy decreases nonlinearly with increasing magnetic field. And the magnetic susceptibility at small values of the magnetic field has a maximum that decreases and tends to zero with increasing magnetic field. With the increase of magnetic field, specific heat and entropy increase non-linearly.

Keywords: Diluted magnetic semiconductor, quantum dot, thermodynamic properties.
