Abstract:An x-ray diffraction study of the growth of Pb1−xMnxTe/PbTe (x=0.022–0.037) multi-quantum well (MQW) structures of period lengths 205–950 Å is presented. In order to obtain a reliable Mn diffusion coefficient at the growth temperature T=270 °C, computed diffusion profiles are used as input for the calculation of diffractograms using kinematical diffraction theory. The satellites of the symmetric (222) Bragg reflections are compared to measurements. The analysis is based on a numerical solution of the diffusion… 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.
