Electrooptic and converse-piezoelectric properties of epitaxial GaN/Si structures for optoelectronic applications

Mireille Cuniot-Ponsard, Irma Saraswati, S.-M. Ko, Mathieu Halbwax, Y.-H. Cho, N.-R. Poespawati, El Hadj Dogheche

In order to take advantage in all-optic optoelectronic devices, we have investigated the optical and piezoelectric properties of GaN films deposited on (111) silicon. Films are epitaxially grown by MOCVD, thanks to a buffer made of (Al, Ga) N intermediate layers [1]. Structural properties of GaN…

Ultrawide-bandwidth single-channel 0.4-THz wireless link combining broadband quasi-optic photomixer and coherent detection

Guillaume Ducournau, P. Szriftgiser, Alexandre Beck, Denis Bacquet, Fabio Pavanello, Emilien Peytavit, Mohammed Zaknoune, Tahsin Akalin, Jean-Francois Lampin

Free space communications with huge data capacity have become a key point for the development of mobile access, services, and network technologies convergence. Wireless links using emerging terahertz technologies, also referred to as T-ray communications, have become an intensive research field…

Disorder-perturbed Landau levels in high-electron-mobility epitaxial graphene

Simon Maëro, Abderrezak Torche, Thanyanan Phuphachong, Emiliano Pallecchi, Abdelkarim Ouerghi, Robson Ferreira, Louis-Anne de Vaulchier, Yves Guldner

We show that the Landau levels in epitaxial graphene in the presence of localized defects are significantly modified compared to those of an ideal system. We report on magnetospectroscopy experiments performed on high-quality samples. Besides typical interband magneto-optical transitions, we…

Electronic and physico-chemical properties of nanometric boron delta-doped diamond structures

Gauthier Chicot, Alexandre Fiori, P.N. Volpe, Thu Nhi Tran Thi, Jean-Claude Gerbedoen, Jessica Bousquet, M.P. Alegre, J.C. Pinero, D. Araujo, F. Jomard, Ali Soltani, Jean-Claude de Jaeger, J. Morse, J. Härtwig, Nicolas Tranchant, C. Mer-Calfati, Jean-Charles Arnault, Julien Delahaye, Thierry Grenet, David Eon, Franck Omnès, Julien Pernot, Etienne Bustarret

Heavily boron doped diamond epilayers with thicknesses ranging from 40 to less than 2 nm and buried between nominally undoped thicker layers have been grown in two different reactors. Two types of [100]-oriented single crystal diamond substrates were used after being characterized by X-ray white…

Cyclones and attractive streaming generated by acoustical vortices

Antoine Riaud, Michael Baudoin, Jean-Louis Thomas, Olivier Bou Matar

Acoustical and optical vortices have attracted great interest due to their ability to capture and manipulate particles with the use of radiation pressure. Here we show that acoustical vortices can also induce axial vortical flow reminiscent of cyclones, whose topology can be controlled by adjusting…
