Abstract

Using time dependent perturbation technique, Stark shift and self-energy correction in semiconductor quantum dot are studied. The analytical results are obtained by incorporating the important excitonic and biexcitonic effects. The numerical estimations are made for potentially important II-VI semiconductor quantum dot CdS of size smaller than the bulk exciton Bohr radius. The demonstration of analytical and numerical result predicts a red shift of (Delta) E/3 with (Delta) E being the biexciton binding energy. The Stark shift and self energy correction are found to have higher amplitudes at high excitation intensities due to the presence of biexcitons.
