Interfacial amplification for graphene-based position-sensitive-detectors

Position-sensitive-detectors (PSDs) based on lateral photoeffect has been widely used in diverse applications, including optical engineering, aerospace and military fields. With increasing demand in long distance, low energy consumption, and weak signal sensing systems, the poor responsivity of conventional PSDs has become a bottleneck limiting its applications. Herein, we present a high performance graphene based PSDs with revolutionary...
