Effects of external fields, the hydrostatic pressure and temperature on the electronic Raman scattering of a hydrogenic impurity in a two-dimensional parabolic quantum dot

Abstract

In this paper, we have investigated the electron Raman scattering associated with a donor impurity in a two-dimensional parabolic quantum dot under the influence of external electric and magnetic fields, the hydrostatic pressure and temperature. To this end, energy eigenvalues and corresponding eigenvectors are calculated using the direct matrix diagonalization method and the differential cross-section is obtained via the Fermi′s golden rule. Our results indicate that the differential cross-section of the system is strongly affected by the external fields, the hydrostatic pressure, temperature, the confinement potential, and the polarization vectors of incident and scattered lights.
