Study of temperature and hydrostatic pressure effect on SHG associated with the excitonic system in an InN Quantum dot

Here, the study of SHG for the correlation of electron- hole in an InN in a semi-parabolic quantum dot with external parameters temperature and hydrostatic pressure has been carried out using effective mass approximation. The density matrix formulations have been used to calculate the eigenvalues and Eigen energies. The dependence of Optical Rectification Coefficient (ORC) on the temperature and hydrostatic pressure in the strong confinement regime for both excitonic as well as without excitonic effects has been investigated. It was found that the ORC is strongly influenced by electron-hole pair localization, temperature change, and alteration in radius and variation in hydrostatic pressure.
