ABSTRACT:
A process for preparing layers with a superficial composition of Hg.sub.1-x Cd.sub.x Te comprising the steps of producing a wafer by forming a layer of superficial composition Hg.sub.1-y Cd.sub.y Te on a substrate of CdTe, y being less than the desired value x, and subjecting this wafer to a thermal interdiffusion treatment at a temperature of between about 350.degree. and about 750.degree. C., under such conditions that the layer of Hg.sub.1-y Cd.sub.y Te cannot decompose.
