Abstract

Multiple quantum wells and superlattices of CdMnTe/CdTe were grown epitaxially on CdZnTe using Pulsed Laser Evaporation and Epitaxy from indium doped Cd_.85Mn_.15Te and high purity CdTe targets. The photoreflectance and photoluminescence spectra were collected at T equals 5-10 K. In addition to the photoreflectance signatures originating from the CdZnTe substrate, CdTe buffer layer and CdMnTe barrier layers, the spectra also display features that are attributed to optical transitions occurring within the CdTe quantum wells. The signatures were observed in several heterostructures with [001], [111], and [112] crystal orientations.
