Development of Time-resolved UV Micro-Raman Spectroscopy to measure temperature in AlGaN/GaN HEMTs

Ophélie Lancry, Emmanuelle Pichonat, Julien Réhault, Myriam Moreau, Raphaël Aubry, Christophe Gaquière

We report on the development of Time-resolved Ultraviolet Micro-Raman Scattering to measure transient self-heating effects in semiconductor devices. Temperature measurements are performed on AlGaN/GaN High-electron-mobility transistors (HEMTs) grown on SiC substrate. Ultraviolet excitation probes…

Transport through open quantum dots : making semiclassics quantitative

I. Brezinova, L. Wirtz, S. Rotter, C. Stampfer, J. Burgdorfer

We investigate electron transport through clean open quantum dots (“quantum billiards”). We present a semiclassical theory that allows to accurately reproduce quantum transport calculations. Quantitative agreement is reached for individual energy and magnetic field dependent elements of the…

Correlation-induced conductance suppression at level degeneracy in a quantum dot

H.A. Nilsson, O. Karlström, M. Larsson, P. Caroff, J.N. Pedersen, L. Samuelson, A. Wacker, L.E. Wernersson, H.Q. Xu

The large, level-dependent g-factors in an InSb nanowire quantum dot allow for the occurrence of a variety of level crossings in the dot. While we observe the standard conductance enhancement in the Coulomb blockade region for aligned levels with different spins due to the Kondo effect, a vanishing…

Calculs de champs acoustiques à l'harmonique 2 par décomposition en faisceaux gaussiens

François Vander Meulen, Lionel Haumesser, Jérôme Fortineau, Olivier Bou Matar

Dans le cadre de l'approximation quasi-linéaire, une solution de l'équation KZK peut être obtenue par la méthode des approximations successives qui, dans ce cas,peut être obtenue par la convolution de la fonction source et d'une fonction de Green de forme gaussienne. Wen et Breazeale…
