Low temperature acoustic phonon limited diffusion thermopower (S d ) in wurtzite ZnO nanowires is studied considering inelasticity of the scattering. An expression for scattering rate due to piezoelectric (PZ) acoustic phonon coupling is given. S d calculated in elastic approximation, used in literature, is found to overestimate. Inclusion of other operative scattering mechanisms obtains agreement with recent thermopower data.
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.
