Abstract
Cu2O nanowires (Nws) network-based heterojunction was observed to have a position-sensitive photovoltaic characteristic. Its amplitude of the photovoltage (Vph) varied regularly with the position of incidence of the 532nm laser radiation onto the Cu2O NWs surface. The Vph of this platform varies with the light position described as ∆Vph/∆x is approximate ~14 mV/mm. Besides, the photoresponse of this device is very stable. This position-sensitive platform is expected to serve as a convenient device as easily to be fabricated, high performing photodetector.
