Photocurrent Enhancement of Graphene Photodetectors by Photon Tunneling of Light into Surface Plasmons

13 Oct 2016 Maleki Alireza Cumming Benjamin P. Gu Min Downes James E. Coutts David W. Dawes Judith M.

We demonstrate that surface plasmon resonances excited by photon tunneling through an adjacent dielectric medium enhance photocurrent detected by a graphene photodetector. The device is created by overlaying a graphene sheet over an etched gap in a gold film deposited on glass... (read more)
