The role of the confined and interface phonon modes in reducing the electron mobility is analyzed separately to permit the identification of the effect of the transversal electric field on this mobility. The electron behavior indicates that electrons of different subbands can be separated in real space by the applied transversal electric field.
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.
