Electronic, optical, and lattice properties of superlattices and heterostructures
Abstract
dc:descriptionUsing an envelope function model, we have calculated the valence band structures in quantum wells and superlattices. It is found that the valence bands exhibit very complicated structures. With the newly devised method and the aid of the CRAY supercomputer, we have been able to calculate the optical absorption spectra for a number of GaAs-Ga$\sb{1-x}$Al$\sb{x}$As superlattices and quantum wells with the valence band mixing included. The results which feature the saddle point exciton resonances in superlattices are in good agreement with the experimental data.
