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…

Metamaterials-inspired technologies applied to ultra high-frequency filtering structures

Alejandro Borja, Jorge Carbonell, Vicente Boria, Michel Chaubet, Didier Lippens

In this letter, the design and comparative study of metamaterial-inspired bandpass filters operating at G-band (150 GHz) is presented. To this aim, filters based on split ring resonators (SRRs) and complementary SRRs are studied and compared on a scale compliant with MMIC technology. Technological…

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…

Calculating Kelvin force microscopy signals from static force fields

Lukasz Borowik, Koku Kusiaku, Didier Theron, Thierry Melin

We present an analytical formula to achieve numerical simulations of Kelvin force microscopy KFM signals from static force fields, which can be employed to describe amplitude-modulation or frequency-modulation KFM, as well as simultaneous topography and KFM modes for which the tip probe exhibits a…

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…
