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…

Photodissociation of hydrogen passivated dopants in gallium arsenide

L. Tong, J.A. Larsson, M. Nolan, M. Murthag, J.C. Greer, M. Barbe, F. Bailly, Jérome Chevalier, S. Sylvestre, D. Loridant-Bernard, E. Constant, M. Constant

A theoretical and experimental study of the photo-dissociation mechanisms of hydrogen passivated n- and p-type dopants in gallium arsenide is presented. The photo-induced dissociation of the SiGa–H complex has been observed for relatively low photon energies (3.48 eV), whereas the photo-…

Determination of elastic constants by line-focus acoustic microscopy : effect of initial Cij values on the Simplex method and influence of geometric probe parameters on the Kushibiki method

Michael Lematre, Youssef Benmehrez, G. Bourse, Wei-Jiang Xu, Mohamed Ourak

The velocity of leaky surface acoustic waves (SAWs) is obtained for different directions of propagation (φ) from the V(z) curves by using the Kuschibiki method. The comparison of measured and calculated velocities consists in the minimization of the summation of the square difference Σ|VΦc-VΦm|2 by…
