Electrooptic and converse-piezoelectric properties of epitaxial GaN/Si structures for optoelectronic applications

Mireille Cuniot-Ponsard, Irma Saraswati, S.-M. Ko, Mathieu Halbwax, Y.-H. Cho, N.-R. Poespawati, El Hadj Dogheche

In order to take advantage in all-optic optoelectronic devices, we have investigated the optical and piezoelectric properties of GaN films deposited on (111) silicon. Films are epitaxially grown by MOCVD, thanks to a buffer made of (Al, Ga) N intermediate layers [1]. Structural properties of GaN…

Theoretical and experimental investigation of Lamb waves characteristics in AlN/TiN and AlN/TiN/NCD composite membranes

Ali Soltani, Abdelkrim Talbi, J-C Gerbedoen, Jean-Claude de Jaeger, Philippe Pernod, V. Mortet, A. Bassam

In this study, we present a theoretical and experimental investigations of the zero order quasi-symmetric (S0) Lamb waves mode propagating in AlN/TiN and AlN/TiN/NCD composite membranes. Theoretical analysis of S0 mode characteristics shows that The AlN/TiN membrane enables to achieve smooth…
