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…
Terahertz surface plasmons in optically pumped graphene structures
A. ~A. ~Dubinov, V. ~Ya. ~Aleshkin, V. ~Mitin +2
We analyze the surface plasmons (SPs) propagating along the optically pumped single-graphene layer (SGL) and multiple-graphene layer (MGL) structures. It is shown that at sufficien…
Analytical device model for graphene bilayer field-effect transistors using weak nonlocality approximation
V. Ryzhii, M. Ryzhii, A. Satou +2
We develop an analytical device model for graphene bilayer field-effect transistors (GBL-FETs) with the back and top gates. The model is based on the Boltzmann equation for the ele…
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…
Epitaxial Graphene on Silicon toward Graphene-Silicon Fusion Electronics
Hirokazu Fukidome, Ryota Takahashi, Yu Miyamoto +8
Graphene is a promising contender to succeed the throne of silicon in electronics. To this goal, large-scale epitaxial growth of graphene on substrates should be developed. Among v…
