Acoustic microscope based on magneto-elastic wave phase conjugator

Andrey Brysev, Leonid Krutyansky, Philippe Pernod, Vladimir Preobrazhensky

Acoustic C-scan imaging (acoustic microscopy) by means of supercritical parametric wave phase conjugation (WPC) is studied experimentally. A phase conjugator based on a magneto-acoustic active material is used for compensating phase distortions introduced by solid and polymer aberration layers...

Uniformity improvement of linear power pHEMTs using a very high selective wet etching

X. Hue, B. Boudart, B. Bonte, Y. Crosnier

The realization and characterization of Al0.22Ga0.78As/In0.22Ga0.78As/GaAs multifinger linear power pHEMTs, using a citric acid selective wet etching for the gate recessing, are reported. A very high uniformity for both the drain current and pinch-off voltage values have been obtained. The...

Interpretation of the Temperature‐Dependent Transport Properties of GaN/Sapphire Films Grown by MBE and MOCVD

J.J. Harris, K Lee, I. Harrison, L. B. Flannery, D. Korakakis, T. S. Cheng, C. T. Foxon, Z. Bougrioua, I. Moerman, W. van Der Stricht, E. J. Thrush, B. Hamilton, K. Ferhah

Electron transport in Si‐doped and unintentionally‐doped GaN films grown on sapphire by MOCVD and MBE has been analysed assuming that a parallel conducting channel, via an impurity band, is present. No dependence on growth method or dopant type was observed, but other trends were apparent: a) the...
