Abstract
We theoretically study the second harmonic generation (SHG) associated with intersubband transitions in semiconductor quantum dots (QDs) emphasizing on the effects of the screened Kratzer (SK) potential parameters and regulating factors, such as temperature and the depth of potential. We apply the Nikiforov-Uvarov-Functional-Analysis (NUFA) method for solving the radial Schrödinger equation. Then, we derive the formulae for the SHG coefficient using the compact-density-matrix method. The results display that the SK potential parameters and the regulating factors play a key role in both the peak and position changes of the SHG in semiconductor QDs system.
