Abstract

Quasi-ballistic electrons injected from the n+ region into the gated n-region of the n+-i-n-n+ graphene FET (GFET) strongly drag the quasi-equilibrium electrons in the n-region. We found that this Coulomb drag can substantially influence the current-voltage characteristics leading to instability of graphene Dirac plasmons and resulting in coherent oscillations/ amplification in the terahertz range.
