Effects of temperature and hydrostatic pressure on the optical rectification associated with the excitonic system in a semi-parabolic quantum dot

Abstract The optical rectification for a GaAs quantum dot with an excitonic system is investigated for the various applied hydrostatic pressure, ambient temperature, and different effective size. The dependence of Optical Rectification Coefficient (ORC) on the temperature, radius and hydrostatic pressure in the strong confinement regime for both excitonic as well as without excitonic effects has been studied. This work demonstrates the intricate dependence of ORC on electron-hole pair localization, temperature change, alteration in radius and variation in hydrostatic pressure.
