Hot Carriers in Graphene

Highly-energetic charge carriers generate voltage when light is absorbed in graphene.  

This image represents a measurement of light-induced voltage with varying amounts of charge carrier density. The S-shaped structure gives evidence of these hot charge carriers, strengthening scientists’ understanding of graphene photodetectors.
