Strain relaxation and thermal effects on the drain conductance in AlGaN/GaN HEMT

A. Telia, A. Bellakhdar, L. Semra, A. Soltani

In this work the effects of technological and electrical parameters of Al m Ga 1-m N/GaN High Electron Mobility Transistors (HEMT) on the output conductance "gd" was studied in the first part. In the second part, the effect on gd of thermal and self heating in the device was analyzed.…

Larges bandes interdites phononiques dans une structure de piliers coniques déposés sur un substrat piézoélectrique

Abdelali Mrabti, Mourad Oudich, Abdellatif Akjouj, Yan Pennec, Bahram Djafari-Rouhani, Abdelkrim Talbi, Jérémy Streque, Yu Du, Ali Soltani, Philippe Pernod

Dans ce papier nous étudions l'existence et le comportement des bandes interdites absolues en dessous de la ligne du son du substrat dans une structure phononique. Le cristal phononique est constitué de piliers coniques de Nickel déposés sur un substrat de Niobate de Lithium (LiNbO3). Nous…

Addition of HfO$_2$ interface layer for improved synaptic performance of phase change memory (PCM) devices

M. Suri, O. Bichler, Q. Hubert, L. Perniola, V. Sousa, C. Jahan, D. Vuillaume, C. Gamrat, B. de Salvo

In this work, we will focus on the use of phase change memory (PCM) to emulate synaptic behavior in emerging neuromorphic system-architectures. In particular, we will show that the performance and energy-efficiency of large scale neuromorphic systems can be improved by engineering individual PCM…

A crown-ether loop-derivatized oligothiophene doubly attached on gold surface as cation-binding switchable molecular junction

T.K. Tran, K. Smaali, M. Hardouin, Q. Bricaud, M. Oçafrain, P. Blanchard, S. Lenfant, S. Godey, J. Roncali, D. Vuillaume

A crown-ether dithiol quaterthiophene is synthesized and immobilized on gold surface by double covalent fixation. UV-vis spectroscopy and cyclic voltammetry show that the corresponding dithioester precursor can complex Pb2+ in solution and that this property is maintained for monolayers of the…

Temperature and damping effects on the frequency dependence of electrostatic force microscopy force gradients

R. Arinero, J. Trasobares, Pascal Girard, M. Ramonda, N. Clément

In this paper we demonstrate that depending on the surrounding ambient, which may be manifested by different damping conditions, a "bump" in frequency response of Electric Force Microscope (EFM) cantilevers may be observed, either in electrical amplitude or phase signals of AC gradients.…

Acoustic wave localization in one-dimensional Fibonacci phononic structures with mirror symmetry

Anne-Christine Hladky, Jerome O. Vasseur, S. Degraeve, C. Granger, M. de Billy

This paper reports on numerical and experimental results of acoustic transmission spectra of bead chains with symmetric and asymmetric Fibonacci-like structures. As a matter of comparison, perfect periodic acoustic waveguide structures are also examined. This study shows that Fibonacci structures…
