Processing and adsorption control in ZnO single nanowire photodetectors

Abstract

ZnO single nanowire photodetectors have been measured in different ambient conditions in order to understand and control adsorption processes on the surface. A decrease in the conductivity has been observed as a function of time when the nanowires are exposed to air, due to adsorbed O<inf>2</inf>/H<inf>2</inf>O species at the nanowire surface. In order to… (More)
