Abstract
A class of ultrasensitive nanoscale hybrid photodetectors formed from carbon electrode-molecule junctions using P3HT:PCBM as photoresponsive semiconductors are demonstrated. The unique device architecture, tunability of nanoscale channel lengths and the optimized contact nature of semiconductor/electrode interfaces led to ultrahigh photogains of 1000 with graphene nanoelectrodes and 1 000 000 with single-walled carbon nanotube nanoelectrodes.
