Abstract

The combined effects of the hydrostatic pressure and temperature on the binding energy, Δ E (transition energy), the oscillator strength and the third-order susceptibility of third harmonic generation (THG) of a hydrogenic impurity in a spherical QD, in the presence of the external electric field, have been investigated by means of the perturbation approach within the framework of effective-mass approximation. It is found that the binding energy, Δ E (transition energy), the oscillator strength and the third-order susceptibility of third harmonic generation (THG) of the hydrogenic impurity are affected by the confinement strength, the electric field, pressure and temperature.
