A compact coplanar waveguide metamaterial-inspired line and its use in tunable narrow bandpass filters

Alejandro Borja, Jorge Carbonell, Vicente Boria, Angel Belenguer, Didier Lippens

In this paper, novel cells, arrays, and reconfigurable metamaterial-inspired coplanar waveguide lines are studied. The novelty stems from the control of the so-called electric and magnetic plasma frequencies by properly designing the loading elements. In particular, wide shunt wires permit one to…

Charged impurity scattering and mobility in gated silicon nanowires

M.P. Persson, H. Mera, Y.M. Niquet, C. Delerue, M. Diarra

We study the effects of charged impurity scattering on the electronic transport properties of h110i-oriented Si nanowires in a gate-all-around geometry, where the impurity potential is screened by the gate, gate oxide and conduction band electrons. The electronic structure of the doped nanowires is…

Asymmetric Franck-Condon factors in suspended carbon nanotube quantum dots

F. Cavaliere, E. Mariani, Renaud Leturcq, C. Stampfer, M. Sassetti

Electronic states and vibrons in carbon nanotube quantum dots have in general different location and size. As a consequence, the conventional Anderson-Holstein model, coupling vibrons to the dot total charge only, may no longer be appropriated in general. Here we explicitly address the role of the…

Nonequilibrium fluctuation relations in a quantum coherent conductor

S. Nakamura, Y. Yamauchi, M. Hashisaka, K. Chida, K. Kobayashi, T. Ono, R. Leturcq, K. Ensslin, K. Saito, Y. Utsumi, A.C. Gossard

We experimentally demonstrate the validity of non-equilibrium fluctuation relations by using a quantum coherent conductor. In equilibrium the fluctuation-dissipation relation leads to the correlation between current and current noise at the conductor, namely, Johnson-Nyquist relation. When the…

Monte Carlo based microscopic description of electron transport in GaAs/Al0.45Ga0.55As quantum-cascade laser structure

P. Borowik, Jean-Luc Thobel, L. Adamowicz

Results of multiparticle Monte Carlo simulations of midinfrared quantum cascade lasers structure initially fabricated by Page et al. are presented. The main aim of this paper is to discuss in details how electric current flows through the structure and which subbands are involved in this process.…

AlGaN/GaN high electron mobility transistors as a voltage-tunable room temperature terahertz sources

A. El Fatimy, N. Dyakonova, Y. Meziani, T. Otsuji, W. Knap, S. Vandenbrouk, K. Madjour, Didier Theron, Christophe Gaquière, M.A. Poisson, S. Delage, P. Pristawko, C. Skierbiszewski

We report on room temperature terahertz generation by a submicron size AlGaN/GaN-based high electron mobility transistors. The emission peak is found to be tunable by the gate voltage between 0.75 and 2.1 THz. Radiation frequencies correspond to the lowest fundamental plasma mode in the gated…
