Efficient physical-thermal model for thermal effects in AlGaN/GaN high electron mobility transistors

Michel Rousseau, A. Soltani, Jean-Claude de Jaeger

This letter describes the thermal behavior of AlGaN/GaN high electron mobility transistors on different substrates thanks to a fully consistent physical-thermal model. Self-heating explains the drastic reduction in the current flowing from drain to source. It is shown that, in order to keep the…

Boron distribution in the core of Si nanowire grown by chemical vapor deposition

W. Chen, V.G. Dubrovskii, X.L. Liu, T. Xu, Rodrigue Lardé, J.P. Nys, B. Grandidier, D. Stievenard, G. Patriarche, Philippe Pareige

The boron dopant distribution in Si nanowires grown by the Au-catalyzed chemical vapor deposition is characterized by laser-assisted atom probe tomography. A convenient and an effective method for performing the atom probe tomography of an individual nanowire is developed. Using this technique, we…

Theoretical and experimental evidence of level repulsion states and evanescent modes in sonic crystal stubbed waveguides

V. Romero-Garcia, Jerome O. Vasseur, Lluis Miquel Garcia-Raffi, Anne-Christine Hladky

The complex band structures calculated using the Extended Plane Wave Expansion (EPWE) reveal the presence of evanescent modes in periodic systems, never predicted by the classical ω(~k) methods, providing novel interpretations of several phenomena as well as a complete picture of the system. In…

Assane Ndieguene

Les recherches menées pour le développement des microsystèmes ont permis d’améliorer considérablement la miniaturisation de certaines fonctions. Ces travaux, très multidisciplinaires, ont conduit à de nombreuses applications dans les domaines des télécommunications, de la chimie et de la biologie.…, The research activities for the development of microsystems enabled the downsizing of many functions. These multidisciplinary works concerns many applications in the fields of telecommunications, chemistry, and biology. In that context, our work concerned the conception and analyses of acoustical…

Level repulsion and evanescent waves in sonic crystals

V. Romero-Garcia, Jerome O. Vasseur, Anne-Christine Hladky, Lluis Miquel Garcia-Raffi, J.V. Sanchez-Perez

This work theoretically and experimentally reports the evanescent connections between propagating bands in periodic acoustic materials. The complex band structures obtained by solving for the k(ω) problem reveal a complete interpretation of the propagation properties of these systems. The…
