An RF spectrometer for fast wide band measurement

Simon Hemour, Florence Podevin, Pascal Xavier

A new type of spectrum analyzer using RF interferometry is presented. The stationary wave integrated Fourier transform spectrometer is dedicated to the measurement of transient wideband signals. The spectrometer is mobile and cheap. It consists of spatial samplers placed along a waveguide ended by…

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…

Large area 0-3 and 1-3 piezoelectric composites based on single crystal PMN-PT for transducer applications

M. Pham Thi, Anne-Christine Hladky, H. Le Khanh, L.P. Tran-Huu-Hue, M. Lethiecq, F. Levassort

0-3 and 1-3 composites have been fabricated using piezoelectric single crystals (PSCs). These two connectivities were specifically chosen for large area fabrication. In particular, a lamination technique was used for 1-3 piezocomposites instead of the standard dice and fill method. For 0-3…

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…

Fabrication and characterization of 200-nm self-aligned In0.53Ga0.47As MOSFET

Aurélien Olivier, Nicolas Wichmann, Jiongjong Mo, Albert M.D. Noudeviwa, Yannick Roelens, L. Desplanque, X. Wallart, Francois Danneville, Gilles Dambrine, S. Bollaert, François Martin, O. Desplats, Jérôme Saint-Martin, Minghua Shi, Y. Wang, M-P Chauvat, P. Ruterana, Hassan Maher

In this paper, a 200 nm n-channel inversion-type self-aligned In 0.53 Ga 0.47 As MOSFET with a Al 2 O 3 gate oxide deposited by Atomic Layer Deposition (ALD) is demonstrated. Two ion implantation processes using silicon nitride side-wall are performed for the fabrication of the n-type source and…
