Abstract:Relations between band-edge discontinuities and interface potential step are derived in theframework of the two-band narrow-gap approach and in terms of gap-attached bulk properties of the two semiconductors in epitaxial contact. The expressions, initially deduced for energy gaps opened a t the centre or edges of the corresponding Brillouin zones, are subsequently extended to include the more general case of gaps opened in other points inside the Brillouin zones.Mit EIilfe der Zweibandapproximation der schmale… 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.
