Oxidation model of polycrystalline lead-chalcogenide layers in an iodine-containing medium

Model concepts of control over the formation of oxide shells in the course of oxidation are confirmed on the basis of experimental results obtained in a study of the fundamental aspects of how nanostructured layers are formed upon diffusion annealing on faceted single crystals of lead chalcogenides. Auger-spectroscopic data on the distribution of the elemental composition over the thickness of layers based on lead selenide–cadmium selenide solid solutions are presented.
