Hopping motion of a particle along a substrate driven by a surface acoustic wave

Marina Terzi, Vladislav Aleshin, Jules Ghesquiere

Manipulation of small objects (particles) lying on vibrating or acoustically excited substrates is of interest for a number of applications such as micro-positioning or acoustic cleaning of surfaces. The objective is to provide a stable directed motion of a particle along a surface supporting a...

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...
