Real-space-transfer mechanism of negative differential conductivity in gated graphene-phosphorene hybrid structures: Phenomenological heating model
V. Ryzhii, M. Ryzhii, D. Svintsov +6
We analyze the nonlinear carrier transport in the gated graphene-phosphorene (G-P) hybrid structures - the G-P field-effect transistors (G-P-FETs) using a phenomenological model. T…
Interband infrared photodetectors based on HgTe--CdHgTe quantum-well heterostructure
V. Ya. Aleshkin, A. A. Dubinov, S. V. Morozov +5
We calculate the characteristics of interband HgTe-CdHgTe quantum-well infrared photodetectors (QWIPs). Due to a small probability of the electron capture into the QWs, the interba…
Interplay of intra- and interband absorption in a disordered graphene
F. T. Vasko, V. V. Mitin, V. Ryzhii +1
The absorption of heavily doped graphene in the terahertz (THz) and mid-infrared (MIR) spectral regions is considered taking into account both the elastic scattering due to finite-…
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…
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…
