Engineered tunneling layer with enhanced impact ionization for detection improvement in graphene/silicon heterojunction photodetectors
Abstract Here, an engineered tunneling layer enhanced photocurrent multiplication through the impact ionization effect was proposed and experimentally demonstrated on the graphene/silicon heterojunction photodetectors. With considering the suitable band structure of the insulation material and their...
