Evidence for Extraction of Photoexcited Hot Carriers from Graphene
Chang-Hua Liu, Nanditha M. Dissanayake, Seunghyun Lee +2
We report evidence of nonequilibrium hot carriers extraction from graphene by gate-dependent photocurrent study. Scanning photocurrent excited by femtosecond pulse laser shows unus…
