Further studies on the lithium phosphorus oxynitride solid electrolyte

T. Pichonat, C. Lethien, Nicolas Tiercelin, S. Godey, E. Pichonat, P. Roussel, Marie Colmont, P.A. Rolland

First step in the way to the fabrication of an all-solid microbattery for autonomous wireless sensor node, amorphous thin solid films of lithium phosphorus oxynitride (LiPON) were prepared by radio-frequency sputtering of a mixture target of P₂O₅/Li<…

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…
