✦ Synopsis

We report on the basic properties of Cd,flrS;Te and CdTe-Cd,$l$Te multilayer structures and superlattices grown by pulsed laser evaporation and epitaxy (PLEE). Two computer controlled XeCl and Nd:YAG lasers are used for simultaneous or sequential vaporization of high-purity polycrystalline targets. The layers are grown on (001) oriented InSb and CdZnTe wafers held at a temperature in the range of 200 -240 "C. In-situ reflection high energy electron diffraction, scanning electron microscopy, energy dispersive x-ray analysis, secondary ion mass spectroscopy, transmission electron microscopy and double crystal x-ray diffraction results have demonstrated that high quality PLEE layers and superlattices can be routinely grown.
