Abstract:GaN /AlGaN transistors are being developed for a variety of RF electronic devices that will eventually replace GaAs-and silicon-based devices for commercial and military applications. In this paper, we present results from the optimization of the growth conditions for GaN/AlGaN HEMT structures. The HEMT epitaxial layers are grown via MOCVD. We demonstrate that the key to high quality HEMT structures is the ability to grow uniform AlGaN layers. Details of the structural, electrical and optical characteristics o… 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.
