Abstract:Differently treated PbTe surfaces have been investigated by means of reflection high energy electron diffraction (RHEEl)) and Euthorford backscattering (RBS). It has been shown that chemical lap polishing followed by heat treatment is the best method to fulfil tho requirements of the following epitaxy process concerning the absence of contaminations, the high structural surface perfection, and the flatness of the substrates.Thc influence of heat treatment on structural perfection and chemical composition in th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
