Multi-phonon scattering processes in one-dimensional anharmonic biological superlattices : understanding the dissipation of mechanical waves in mineralized tissues

Pierre-Yves Guerder, Alix C. Deymier-Black, Nichlas Z. Swinteck, Jerome O. Vasseur, Olivier Bou Matar, Krishna Muralidharan, Pierre A. Deymier

The scattering of elastic waves in a one dimensional phononic (PnC) crystal composed of alternate collagen and hydroxy-apatite constituent layers is studied. These superlattices are metaphors for mineralized tissues present in bones and teeth. The collagen is treated as an open system elastic...

Optimized V-shape design of GaN nanodiodes for the generation of Gunn oscillations

J.F. Millithaler, I. Iniguez-De-La-Torre, A. Iniguez-De-La-Torre, T. Gonz Alez, P. Sangaré, Guillaume Ducournau, Christophe Gaquière, J. Mateos

In this work, recent advances in the design of GaN planar Gunn diodes with asymmetric shape, socalled self-switching diodes, are presented. A particular geometry for the nanodiode is proposed, referred as V-shape, where the width of the channel is intentionally increased as approaching the anode....

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...

Step-conformal deposition of TiO2 and MnO2 electrodes on advanced silicon microstructures for 3D Li-ion microbatteries and micro-supercapacitors

Étienne Eustache, Camille Douard, Pascal Tilmant, Laurence Morgenroth, Pascal Roussel, Thierry Brousse, Christophe Lethien

To get autonomous smart microsystem, a miniaturized power source should be integrated. As the device is surface limited, the energy and power performances of commercially available planar microbatteries and micro-supercapacitors are not sufficient to reach this goal. To improve their performances...

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...
