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…

Supercritical parametric phase conjugation of ultrasound. Numerical simulation of nonlinear and nonstationary mode

Alain Merlen, Vladimir L. Preobrazhensky, Philippe Pernod

This paper investigates the saturation mechanism of the nonstationary supercritical mode of parametric wave phase conjugation in a magnetostrictive medium. The numerical simulation considers the two most probable nonlinear mechanisms of interaction between elastic deformation and electromagnetic…
