Imagerie passive de couches sur substrats par corrélation de champ acoustique haute fréquence

Nada Ben Jafela, Lynda Chehami, Marc Duquennoy, Emmanuel Moulin, Nikolay Smagin, Dame Fall, Zakariae Oumekloul

Les structures couche sur substrat sont généralement sujettes à divers types de défauts, en particulier ceux liés au processus de fabrication lors de la croissance des films minces. Actuellement, une possibilité pour inspecter ces structures consiste à utiliser des transducteurs IDTs en émission et...

A Theoretical Analysis of the Frequency Response in p-i-n Photodiodes that Use InGaAs/InP Materials

Nesrine Bakalem, Abdelkader Aissat, Samuel Dupont, Faouzi Saidi, Mohamed Houcine Dhaou, Jean Pierre Vilcot

This investigation is centered on the analysis of frequency response characteristics of a p-i-n photodiode using InxGa$_{1-x}$As/InP. The InGaAs/InP can be developed under three conditions: compression, tensile strain, and lattice matching. Initially, we performed calculations on strain, bandgap...

Modeling Mechanical Micro-instabilities in Biophysics and Materials Science

Andrea Cannizzo, Manon Benedito, Fabio Manca, Stefano Giordano

From biophysics to materials science, mechanical micro-instabilities play a central role in a multitude of materials and structures (adhesion, fracture, friction, phase transformations and so on). Although these systems are very different in length-scale, time-scale and morphology, they are all...
