Simulation of excitonic spectra in electric field to characterize the quality of low dimensional structures

In order to characterize the real low dimensional structures, the simulation of excitonic spectra has been done. Absorption spectrum of multiple quantum well MQW.in graded electric field, the effect of macroscopic quantum well width and depth fluctuations, and the influence of surface roughness have been considered. The simulated spectra are in a good agreement with experimental data. q2000 Published by Elsevier Science B.V.
