title = "Terahertz gain and amplification in current-driven metasurfaces of graphene Dirac plasmons",
abstract = "We explore current-driven Dirac plasmon dynamics in monolayer graphene metasurfaces. DC-current-induced complete suppression of the graphene absorption is experimentally observed in a broad frequency range followed by a giant amplification (up to ∼9 % gain) of an incoming terahertz radiation at room temperature.",
