Thin films of InAs1−xSbx (0<x<1) have been deposited on GaAs and InSb substrates in the temperature range 300–400 °C using molecular beam epitaxy. The solid composition was found to be quite sensitive to the Sb flux and less sensitive to As flux. InSb-InAsSb superlattice structures have also been grown and studied. Both the ternary alloy and the superlattice structures can be potential material systems for detectors covering the 8–12-μ range.
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.
