Experimental demonstration of direct terahertz detection at room-temperature in AlGaN/GaN asymmetric nanochannels

Paul Sangare, Guillaume Ducournau, Bertrand Grimbert, Virginie Brandli, Marc Faucher, Christophe Gaquière, Ana Iniguez-De-La-Torre, Ignacio Íñiguez-De-La-Torre, Jean-Francois Millithaler, Javier Mateos, Tomás González

The potentialities of AlGaN/GaN nanodevices as THz detectors are analyzed. Nanochannels with broken symmetry (so called self switching diodes) have been fabricated for the first time in this material system using both recess-etching and ion implantation technologies. The responsivities of both…

A fully distributed non linear waveguide using (Pb,Sr)TiO3 thin film : second and third harmonics generation

Freddy Ponchel, Ludovic Burgnies, D. Ducatteau, Eric Lheurette, Denis Remiens, D. Lippens

We report on the experimental investigation of a non-linear (NL) Co-Planar Waveguide (CPW) fabricated by means of a ferroelectric film. In contrast to conventional NL-CPW, periodically loaded by lumped varactors, the tunable ferroelectric material is fully distributed along the propagation…

An interferometric scanning microwave microscope and calibration method for sub-fF microwave measurements

Thomas Dargent, Kamel Haddadi, T. Lasri, N. Clément, D. Ducatteau, Bernard Legrand, H. Tanbakuchi, Didier Theron

We report on an adjustable interferometric set-up for Scanning Microwave Microscopy. This interferometer is designed in order to combine simplicity, a relatively flexible choice of the frequency of interference used for measurements as well as the choice of impedances range where the interference…

Raman spectroscopy of self-catalyzed GaAs1-xSbx nanowires grown on silicon

Esther Alarcon Llado, Sònia Conesa-Boj, X. Wallart, Philippe Caroff, Anna Fontcuberta I Morral

Thanks to their wide band structure tunability, GaAs1−xSbx nanowires provide exciting perspectives in optoelectronic and energy harvesting applications. The control of composition and strain of these ternary alloys is crucial in the determination of their optical and electronic properties. Raman…

Effect of antimony on structure strained quantum well laser

Abdelkader Aissat, Farid Ykhlef, Said Nacer, Jean-Pierre Vilcot

This work consists of highly strained quantum well GaxIn1-xNyAs1-y-zSbz quaternary structure modeling. We have studied the effect nitrogen and antimony incorporation into ternary semiconductor III-V alloys. We found that incorporating nitrogen in the structure leads to a splitting of the conduction…

Shift and torsion contact problems for arbitrary axisymmetric normal stress distributions

Grey Sh Boltachev, Vladislav Aleshin

In this paper, we analyze the contact interaction of axisymmetric particles subject to a subsequent application of a constant normal load and a tangential or rotational force. A rigorous solution to the frictional contact problem is given by the known Jäger theorem that presents a relationship…
