Abstract

The present study investigates the effect of impurity type on the electronic structure and thermodynamic properties of a two-dimensional Gaussian quantum dot. The energy spectrum of the system was determined by the two-dimensional diagonalization method within the framework of the effective mass approach. The findings of the present study indicate that the effective confinement potential varies by the type of Gaussian impurity. This observation consequently gives rise to significant alterations in the electronic energy spectrum and thermodynamic properties. It was also determined that the impurity location has a remarkable effect on the energy spectrum and thermodynamic quantities. The impurity type and temperature have significant effects on this phenomenon. It is anticipated that the results obtained will provide valuable contributions to the experimental studies to be carried out in the design and development of optoelectronic devices based on doped semiconductor quantum dots.
