Abstract

Cd_0.90Mn_0.10Te/CdTe heterostructures grown on CdZnTe substrates by pulsed laser evaporation and epitaxy have been studied by low temperature photoluminescence. The structures were grown from fluxes of Cd-Te and Cd-Mn-Te resulting from the ablation of solid CdTe and Cd_1-xMn_xTe targets with Nd:YAG and excimer XeCl lasers, respectively. The samples chosen for this work are multiple quantum wells (MQW) and superlattices (SL) with buffer and cap layers of various thicknesses and compositions. They have a fixed nominal quantum well width of 2 nm and barriers varying between 4.5 and 16.5 nm, with several combinations of CdTe and Cd_0.90Mn_0.10Te buffer and cap layers.
