Abstract
A study of the optical properties of short-period GaP/InP(001) straine d-layer superlattices is presented. photoluminescence, photoreflectanc e, and resonant Raman spectroscopies have been used to determine both the interband transition energies and the spatial distribution of the electronic wave functions. Comparison of the experimental results to t hose of an empirical tight-binding calculation provides an overall pic ture of the superlattices's electronic structure, and gives an estimat e of the valence-band offset of about 0.6 eV.
