ABSTRACT:
An improved method of forming a ZnS layer on a ZnSe substrate by chemical vapor deposition of ZnS onto the ZnSe is disclosed in which the ZnS is contacted, prior to the chemical vapor deposition of the ZnS, with H.sub.2 S in the absence of zinc metal vapor to cause reaction of the H.sub.2 S and the surface of the ZnSe substrate.
