On the effect of δ-doping in self-switching diodes

Andreas Westlund, Ignacio Iñiguez-De-La-Torre, Per-Åke Nilsson, Tomas González, Javier Mateos, Paul Sangaré, Guillaume Ducournau, Christophe Gaquière, L. Desplanque, Xavier Wallart, Jan Grahn

Lowering the carrier concentration is presented as a way to considerably improve the performance of self-switching diode (SSD) detectors. A physics-based theoretical model was used to derive an expression for the responsivity of SSDs as a function of carrier concentration, mobility, and design...

A real-time terahertz beam monitoring application with a 1024-pixel CMOS terahertz camera module

Richard Al Hadi, Jean-Francois Lampin, Ullrich Pfeiffer

In this paper a terahertz beam monitoring application of an optically pumped molecular terahertz laser with a 1024-pixel CMOS terahertz camera is presented. The terahertz camera has been used to detect variations in real-time of the terahertz source beam around 2.52 THz.

Current-voltage characteristics of (Mo/Au)/AlGaN/GaN/Si Schottky diodes

H. Mosbahi, M. Charfeddine, M. Gassoumi, Christophe Gaquière, M.A. Zaidi, H. Maaref

The AlGaN/GaN high electron mobility transistors (HEMTs) is a promising candidate for microwave applications due to its high power and high temperature. owing to their large and direct band gap, as well as favorable transport properties. Moreover, III-V nitrides could be suitable for the emitters...

Approach-to-equilibrium molecular dynamics for thermal conductivies and boundary conductances

Pier Luca Palla, Evelyne Lampin, Pierre-Arnaud Francioso, Fabrizio Cleri

Thermal transport is simulated at the atomic scale by approach-to-equilibrium molecular dynamics simulations (AEMD) [1]. In this method, a hot and a cold regions are delimited, before the approach-to-equilibrium is simulated by releasing the thermal constraint. The temperature difference between...

Measurement of the thermal conductivity of polydimethylsiloxane polymer using the three omega method

Nadine Al-Khudary, Pierre-Yves Cresson, Yovan Orlic, Philippe Coquet, Philippe Pernod, T. Lasri

Polydimethylsiloxane (PDMS) has widely appeared in different electronic and medical applications. The knowledge of the thermal properties of PDMS and especially its thermal conductivity is required while processing PDMS to design a particular device. In this paper measurement of the thermal...

Synthesis and electrical characterisations of a low work function cesium oxide coating for high efficiency thermionic energy converter

François Morini, J.F. Robillard, Stéphane Monfray, I.D. Baikie, Thomas Skotnicki, Emmanuel Dubois

One main challenge associated with solid-state thermoelectric materials is to combine electron-crystal electrical conductivity and phonon-glass thermal properties that are difficult to conciliate. A markedly different principle of thermoelectric conversion is based on the micro-thermionic generator...

Dispersion properties and low infrared optical losses in epitaxial AlN on sapphire substrate in the visible and infrared range

Ali Soltani, Arnaud Stolz, Joël Charrier, Maghnia Mattalah, Jean-Claude Gerbedoen, Hassan Ali Barkad, Vincent Mortet, Michel Rousseau, Nour Eddine Bourzgui, Ali Benmoussa, Jean-Claude de Jaeger

Optical waveguiding properties of a thick wurtzite aluminum nitride highly [002]-textured hetero-epitaxial film on (001) basal plane of sapphire substrate are studied. The physical properties of the film are determined by X-ray diffraction, atomic force microscopy, microRaman, and photocurrent...
