Graphene vertical cascade interband terahertz and infrared photodetectors
V. Ryzhii, T. Otsuji, M. Ryzhii +5
We propose and evaluate the vertical cascade terahertz and infrared photodetectors based on multiple-graphene-layer (GL) structures with thin tunnel barrier layers (made of tungste…
Negative dynamic Drude conductivity in pumped graphene
D. Svintsov, V. Ryzhii, T. Otsuji
We theoretically reveal a new mechanism of light amplification in graphene under the conditions of interband population inversion. It is enabled by the indirect interband transitio…
Graphene nanoelectromechanical resonators for detection of modulated terahertz radiation
D. Svintsov, V. G. Leiman, V. Ryzhii +2
We propose and analyze the detector of modulated terahertz (THz) radiation based on the graphene field-effect transistor with mechanically floating gate made of graphene as well. T…
Carrier-carrier scattering and negative dynamic conductivity in pumped graphene
Dmitry Svintsov, Victor Ryzhii, Akira Satou +2
We theoretically examine the effect of carrier-carrier scattering processes (electron-hole and electron-electron) on the intraband radiation absorption and their contribution to th…
