Waves in periodic media : Fourier analysis shortcuts and physical insights, case of 2D phononic crystals

Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik

Phononic crystal is a structured media with periodic modulation of its physical properties that influences the propagation of elastic waves and leads to a peculiar behaviour, for instance the phononic band gap effect by which elastic waves cannot propagate in certain frequency ranges. The...

On wafer silicon integrated noise source characterization up to 110 GHz based on germanium-on-silicon photodiode

Sandrine Oeuvrard, Jean-Francois Lampin, Guillaume Ducournau, Sylvie Lepilliet, Francois Danneville, Thomas Quemerais, Daniel Gloria

In this work, a new concept of photonic noise source has been developed and characterized, based on Germanium-on-Silicon high speed photodiode (GeHSPD). This photodiode RF output power has been preliminary characterized up to 210 GHz, using a dedicated optoelectronic bench and demonstrating...

Croissance localisée d'InAs par épitaxie par jets moléculaires

Maria Fahed, L. Desplanque, Xavier Wallart

Ce travail porte sur l'étude de la croissance localisée d'InAs sur InAs déposé par épitaxie par jets moléculaires (EJM). Nous présentons la caractérisation de la morphologie des surfaces par microscopie électronique à balayage (MEB).

InAs based Esaki tunnel diodes

Vinay Kumar Chinni, L. Desplanque, Mohamed Zaknoune, Xavier Wallart

We present simulation results of InAs based Esaki tunnel diodes. InAs homojunction and InAs/AlGaSb heterojunction are considered and we investigate the role of source and drain doping levels as well as band energy discontinuities on the tunneling current of the device. The results are very...

F center in lithium fluoride revisited : comparison of solid-state physics and quantum-chemistry approaches

Ferenc Karsai, Paul Tiwald, Robert Laskowski, Fabien Tran, David Koller, Stefanie Gräfe, Joachim Burgdörfer, Ludger Wirtz, Peter Blaha

We revisit the theoretical description of the F color center in lithium fluoride employing advanced complementary ab initio techniques. We compare the results from periodic supercell calculations involving density-functional theory (DFT) and post-DFT techniques with those from the embedded-cluster...
