Abstract:
In this paper we have studied the spectrum of an off-center donor impurity confined in the conical quantum dot with spherical edge surrounded by finite and infinite confinement potential. By considering the effective mass approximation and using the finite difference and elements method, we have obtained the eigenenergies and the eigenfunctions of the nanosystem. The hydrostatic pressure and temperature effects as well as the displacement of the donor on the binding energy are investigated. It is noted that the binding energy increases with hydrostatic pressure and decreases with temperature. Additionally, the results show that the diamagnetic susceptibility increases with the conical angle and decreases with the dot radius. These different influences allow a good understanding of the spectrum of these nanoparticles, and facilitate the fabrication of new optoelectronic devices.
