Hot-Carrier Seebeck Effect: Diffusion and Remote Detection of Hot Carriers in Graphene.

Abstract

We investigate hot carrier propagation across graphene using an electrical nonlocal injection/detection method. The device consists of a monolayer graphene flake contacted by multiple metal leads. Using two remote leads for electrical heating, we generate a carrier temperature gradient that results in a measurable thermoelectric voltage V(NL) across the… (More)
