Position-sensitive-detectors (PSDs) based on lateral photoeffect have been widely used in diverse appfications1-9,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 their applications,for example,silicon p-n or p-i-n junctions2-5,or other materials and architectures6-10.Herein,we present a high-performance graphene-based PSDs with revolutionary interfacial amplification mechanism.
