Abstract:Owing to the intrinsic nanoscale dimension of two-dimensional (2D) piezoelectric semiconductors, the small-scale effects on their piezopotential properties are inevitable in their piezotronic applications. In this work, based on the nonlocal constitutive relations and the phenomenological theory of piezoelectric semiconductors, the small-scale effects are incorporated into the continuum modelling of the piezopotential for 2D semiconductors. After a linearized analysis is performed to the newly proposed nonloca… 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.
