Fabrication of InAs/AlGaSb quantum wire transistors (QWTs) and quasi-one-dimensional(1D) transport properties are reported. Low-dimensional electron transport properties were characterized by magneto-transport measurements at 4.2K. We have succeeded in a decent demonstration of QWTs with narrow channels down to lOOnm width. The transconductance in multiple QWTs with various wire width are compared to discuss 1 D electron transport properties.
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.
