Multiple parallel conduction paths observed in depth-profiled n-GaN epilayers

C. Mavroidis, J. Harris, R. Jackman, I. Harrison, B. Ansell, Z. Bougrioua, I. Moerman

We have combined plasma etching with the Hall effect and resistivity measurements between 10 and 300 K to study the depth distribution of conduction in silicon (Si)-doped GaN epitaxial layers grown on sapphire substrates by two different metalorganic chemical vapor deposition processes. Reduction…

Microwave technique for detection, location and sizing of buried objects

Latifa Achrait-Furlan, T. Lasri, Ahmed Mamouni

The detection, location, and sizing of immersed objects in a host medium are tasks of interest in many fields. One of the most suitable tools for the noninvasive measurements of buried objects is the use of microwaves. We propose in this paper a microwave method based on the knowledge of the…

Critical angular dependance of the polarising field on the magnetoelastic dynamics near the SRT in TbFe/FeCo multilayers

Nicolas Tiercelin, Vladimir Preobrazhensky, Jamal Ben Youssef, Philippe Pernod, Henri Le Gall

Summary form only given. We reflect the results of the latest investigations on giant magnetostrictive multilayers in which a field induced spin reorientation transition (SRT) is used to develop new ways of control for magnetostrictive MEMS such as the possibility of "sub-harmonic"…
