Graphene vertical hot-electron terahertz detectors
V. Ryzhii, A. Satou, T. Otsuji +3
We propose and analyze the concept of the vertical hot-electron terahertz (THz) graphene-layer detectors (GLDs) based on the double-GL and multiple-GL structures with the barrier l…
Damping of Terahertz Plasmons in Graphene Coupled with Surface Plasmons in Heavily-Doped Substrate
A. Satou, Y. Koseki, V. Ryzhii +2
Coupling of plasmons in graphene at terahert (THz) frequencies with surface plasmons in a heavily-doped substrate is studied theoretically. We reveal that a huge scattering rate ma…
Transient stimulated emission from multi-split-gated graphene structure
A. Satou, F. T. Vasko, T. Otsuji +1
Mechanism of transient population inversion in graphene with multi-splitted (interdigitated) top-gate and grounded back gate is suggested and examined for the mid-infrared (mid-IR)…
Double injection in graphene p-i-n structures
V. Ryzhii, I. Semenikhin, M. Ryzhii +4
We study the processes of the electron and hole injection (double injection) into the i-region of graphene-layer and multiple graphene-layer p-i-n structures at the forward bias vo…
Dynamic effects in double graphene-layer structures with inter-layer resonant-tunneling negative conductivity
V. Ryzhii, A. Satou, T. Otsuji +3
We study the dynamic effects in the double graphene-layer (GL) structures with the resonant-tunneling (RT) and the negative differential inter-GL conductivity. Using the developed…
Teraherz photomixing using plasma resonances in double-graphene layer structures
V. Ryzhii, M. Ryzhii, V. Mitin +3
We propose the concept of terahertz (THz) photomixing enabled by the interband electron transitions due to the absorption of modulated optical radiation in double-graphene layer (d…
