A 1 GHz SAW oscillator on epitaxial GaN/Si substrate : toward co-integrated frequency sources

M. Faucher, G. Martin, J.M. Friedt, S. Ballandras

GaN is an attractive material for the fabrication of various integrated devices combining several physical effects (semi-conductors, piezoelectric and optic parts, etc.). This work is dedicated to the investigation of GaN for the fabrication of surface acoustic wave oscillators. The first…

In situ high-temperature characterization of AlN-based surface acoustic wave devices

T. Aubert, Jochen Bardong, Ouarda Legrani, O. Elmazria, M. Badreddine Assouar, Gudrun Bruckner, Abdelkrim Talbi

We report on in situ electrical measurements of surface acoustic wave delay lines based on AlN/sapphire structure and iridium interdigital transducers between 20 °C and 1050 °C under vacuum conditions. The devices show a great potential for temperature sensing applications. Burnout is only observed…

Micromachined high-frequency ZnO ultrasonic linear arrays

Jin-Ying Zhang, Wei-Jiang Xu, G. Han, Julien Carlier, X.M. Ji, S.M. Chen, B. Xu

ZnO thin film has been widely applied in highfrequency acoustic microscopy using single element transducer. It needs mechanical scanning which is much more timeconsuming than electronic scanning with transducer array. However, one of the challenges in the implementation of ZnO transducer array is…

Global transmission and reflection coefficients of the ultrasonic component in porous media : a new approach

Georges Nassar, Amina Medjdoub, N. Saad

The purpose of this paper is to propose a new approach to determining the global ultrasonic transmission and reflection coefficients in a random porous medium. Boundary conditions at the interface of the medium were used to determine local transmission and reflection coefficients. A study of the…

Electron delay analysis and image charge effect in AlGaN/GaN HEMT on silicon substrate

Alain Agboton, N. Defrance, Philippe Altuntas, Vanessa Avramovic, Adrien Cutivet, Rezki Ouhachi, Jean-Claude de Jaeger, Samira Bouzid-Driad, Maher, Hassan, M. Renvoise, Peter Frijlink

A delay time analysis is carried out for SiN-passivated AlGaN/GaN High Electron Mobility Transistors (HEMTs) on silicon substrate featuring gate length of 90 nm. The influence of high parasitics in the access pads is considered using de-embedding procedure from the measured S parameters. From the…
