ELECTRODEPOSITION OF METAL SULFIDE SUPERLATTICES

Polycrystalline superlattice structures in the systems Cd-M-S (M = Zn, Hg, Pb) are for the first time prepared by pulsed electrodeposition a nd characterized by Rutherford backscattering spectrometry, x-ray diff raction, and electron microscopy. The thin-film structures consist of periodically alternating hexagonal Cd1-xMxS solid-solution layers diff ering in composition. The periods of the superlattices are determined. It is shown that, by varying deposition conditions, it is possible to produce amorphous Cd-M-S superlattice structures, as well as structur es based on MS sulfides.
