Amplified Stimulated Terahertz Emission at Room temperature from Optically Pumped Graphene
Stephane Boubanga Tombet, Silvia Chan, Taiichi Otsuji +2
Room temperature Terahertz stimulated emission and population inversion in optically pumped graphene is reported. We experimentally observe fast relaxation and relatively slow reco…
Observation of Amplified Stimulated Terahertz Emission from Optically Pumped Epitaxial Graphene Heterostructures
Taiichi Otsuji, Hiromi Karasawa, Tsuneyoshi Komori +5
We experimentally observe the fast relaxation and relatively slow recombination dynamics of photogenerated electrons/holes in an epitaxial graphene-on-Si heterostructure under pump…
Nonequilibrium carriers in an intrinsic graphene under interband photoexcitation
A. Satou, F. T. Vasko, V. Ryzhii
We study nonequilibrium carriers (electrons and holes) in an intrinsic graphene at low temperatures under far- and mid-infrared (IR) radiation in a wide range of its intensities. T…
