Conception dun microsystème acoustique permettant la caractérisation ultrasonore haute fréquence en transmission

Assane Ndieguene, Shengxiang Wang, Julien Carlier, Pierre Campistron, Wei-Jiang Xu, Dorothée Debavelaere-Callens, Bertrand Nongaillard, Xingzhong Zhao

Lintégration de miroirs à 45° dans des substrats de silicium a permis de générer des ondes ultrasonores longitudinales ou transversales hautes fréquences, dans une direction parallèle au plan de la surface. Cette disposition permet de dissocier la face du wafer utilisée pour intégrer les éléments…

Ab initio calculation of the binding energy of impurities in semiconductors : application to Si nanowires

Y.M. Niquet, L. Genovese, C. Delerue, T. Deutsch

We discuss the binding energy Eb of impurities in semiconductors within density functional theory (DFT) and the GW approximation, focusing on donors in nanowires as an example. We show that DFT succeeds in the calculation of Eb from the Kohn-Sham (KS) hamiltonian of the ionized impurity, but fails…

Microwave modulation of terahertz quantum cascade lasers : a transmission-line approach

Wilfried Maineult, Lu Ding, Pierre Gellie, Pascal Filloux, Carlo Sirtori, Stefano Barbieri, Tahsin Akalin, Jean-Francois Lampin, Isabelle Sagnes, Harvey E. Beere, David Ritchie

We report on microwave impedance measurements of metal-metal ridge-waveguide terahertz quantum cascade lasers. Experimental data, recorded at 4 K in the 100 MHz–55 GHz range, are well reproduced by distributed-parameter transmission-line simulations, showing that the modulation cutoff is limited by…

Graphene growth by molecular beam epitaxy on the carbon-face of SiC

E. Moreau, S. Godey, F.J. Ferrer, D. Vignaud, X. Wallart, J. Avila, M.C. Asensio, F. Bournel, J.J. Gallet

Graphene layers have been grown by molecular beam epitaxy (MBE) on the (0001¯) C-face of SiC and have been characterized by atomic force microscopy, low energy electron diffraction (LEED), and UV photoelectron spectroscopy. Contrary to the graphitization process, the step-terrace structure of SiC…
