Negative refraction of elastic waves in 2D phononic crystals : contribution of resonant transmissions to the construction of the image of a point source

Anne-Christine Hladky, Charles Croënne, Bertrand Dubus, Jerome O. Vasseur, L. Haumesser, D. Manga, B. Morvan

Negative refraction properties of a two-dimensional phononic crystal (PC), made of a triangular lattice of steel rods embedded in epoxy are investigated both experimentally and numerically. First, experiments have been carried out on a prism shaped PC immersed in water. Then, for focusing purposes...

Thermal characterization of MBE-grown GaN/AlGaN/GaN device on single crystalline diamond

J. Kuzmik, S. Bychikhin, D. Pogany, E. Pichonat, O. Lancry, Christophe Gaquière, G. Tsiakatouras, G. Deligeorgis, A. Georgakilas

Self-heating effects in a molecular beam epitaxy-grown GaN/AlGaN/GaN structure on a single crystalline diamond is investigated. A transient interferometric method, in combination with a three dimensional model, is used to describe a pulsed operation of a transistor-like heater, and a micro-Raman...

Electrical characterization of (Ni/Au)/Al0.25Ga0.75N/GaN/SiC Schottky barrier diode

S. Saadaoui, M.M. Ben Salem, M. Gassoumi, H. Maaref, Christophe Gaquière

In this work we report on the characteristics of a (Ni/Au)/AlGaN/GaN/SiC Schottky barrier diode (SBD). A variety of electrical techniques, such as gate current-voltage (I-V), capacitance-voltage (C-V), and deep level transient spectroscopy (DLTS) measurements have been used to characterize the...

Dielectric dispersion of BaSrTiO3 thin film from centimeter to submillimeter wavelengths

Grégory Houzet, Karine Blary, Sylvie Lepilliet, Didier Lippens, Ludovic Burgnies, Gabriel Vélu, Jean-Claude Carru, Edwin Nguema Agnandji, Patrick Mounaix

The dielectric dispersion of ferroelectric BaxSr1-xTiO3 (BST) thin film in a paraelectric phase was characterized from centimeter to submillimeter wavelengths. To this aim, interdigitated capacitors were patterned on a micrometer scale onto a BST layer with a barium concentration of 0.5 and were...
