摘要：
Optical absorption coefficient for vertical valence-band-to-conduction-band transitions in ZnSe-ZnS strained-layer superlattices is studied theoretically. The calculations of the electronic states near the band edges are carried out by using the Kronig-Penney model with the Luttinger-Kohn Hamiltonian. It is shown that the overall features of the absorption spectrum observed by Shen et al. are explained fairly well, and it is predicted that a change of polarization for incident photons produces a significant modification in the absorption spectrum.
