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…

Numerical and experimental investigation of kerf depth effect on high-frequency phased array transducer

Jin-Ying Zhang, Wei-Jiang Xu, Julien Carlier, X.M. Ji, S. Queste, Bertrand Nongaillard, Y.P. Huang

Background High-frequency ultrasonic transducer arrays are essential for high resolution imaging in clinical analysis and Non-Destructive Evaluation (NDE). However, the structure design and fabrication of the kerfed ultrasonic array is quite challenging when very high frequency (⩾100 MHz) is…

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…
