Graphene terahertz uncooled bolometers
V. Ryzhii, T. Otsuji, M. Ryzhii +4
We propose the concept of a terahertz (THz) uncooled bolometer based on n-type and p-type graphene layers (GLs), constituting the absorbing regions, connected by an array of undope…
Effect of plasma resonances on dynamic characteristics of double graphene-layer optical modulator
V. Ryzhii, T. Otsuji, M. Ryzhii +4
We analyze the dynamic operation of an optical modulator based on double graphene-layer(GL) structure utilizing the variation of the GL absorption due to the electrically controlle…
Effect of self-consistent electric field on characteristics of graphene p-i-n tunneling transit-time diodes
V. L. Semenenko, V. G. Leiman, A. V. Arsenin +4
We develop a device model for p-i-n tunneling transit-time diodes based on single- and multiple graphene layer structures operating at the reverse bias voltages. The model of the g…
Hydrodynamic model for electron-hole plasma in graphene
D. Svintsov, V. Vyurkov, S. Yurchenko +2
We propose a hydrodynamic model describing steady-state and dynamic electron and hole transport properties of graphene structures which accounts for the features of the electron an…
