Active control of a piezoelectric phononic crystal using electrical impedance

Sid Ali Mansoura, Pierre Maréchal, Bruno Morvan, Anne-Christine Hladky, Bertrand Dubus

We consider a one dimensional Phononic Crystal (PC) based on a stack of plates including piezoelectric layers. The model takes into account electrical external circuit connected to the piezoelectric layers with the exception of the layer for which the impedance is evaluated. Only longitudinal waves…

Interferometric Near-field Microwave Microscopy Platform for Electromagnetic Micro-analysis

Kamel Haddadi, Jaouad Marzouk, Sijia Gu, S. Arscott, Gilles Dambrine, Tuami Lasri

We report an original near-field microwave microscope based on an interferometric technique for dielectric characterization in liquid media. The instrumentation combines a vector network analyzer, an interferometry-based matching network and dedicated evanescent microstrip probes fabricated in…

Magneto-transport subband spectroscopy in InAs nanowires

Florian Vigneau, Vladimir Prudkovskiy, Ivan Duchemin, Walter Escoffier, Philippe Caroff, Yann-Michel Niquet, Renaud Leturcq, Michel Goiran, Bertrand Raquet

We report on magnetotransport measurements in InAs nanowires under a large magnetic field (up to 55 T), providing a spectroscopy of the one-dimensional electronic band structure. Large modulations of the conductance mediated by a control of the Fermi energy reveal the Landau fragmentation, carrying…

Speech communication

Nicolas Côté, Jens Berger

The goal of any speech service is the transmission and/or processing of speech signals. In this chapter we discuss the Quality of Experience (QoE) of speech communication systems, including networks, speech processing applications and terminals. We then give an overview of the methods employed to…

InAs/AlGaSb Esaki tunnel diodes grown by selective area epitaxy on GaSb (001) substrate

L. Desplanque, Xianglei Han, Maria Fahed, Vinay K. Chinni, David Troadec, M.-P. Chauvat, Pierre Ruterana, Xavier Wallart

We report on the realization of AlGaSb/InAs Esaki tunnel diodes on GaSb (001) substrate. Selective area molecular beam epitaxy of InAs is used to define the area of the diodes down to submicron dimensions. A peak current density up to 1.3 MA/cm2 is achieved.
