Room Temperature Amplification of Terahertz Radiation by Grating-Gate Monolayer Graphene-Channel Transistor Structures

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Using monolayer graphene grating gate structures, we demonstrate tunable resonant plasmon absorption which, with an increase of the current, turns to THz radiation amplification. The observed gain of up to 9% is far beyond the well-known landmark level of 2.3% that is maximal available in monolayer graphene when photons directly interact with electrons.
