Energy transfer between acoustic fields by dry frictional contacts for SHM: a lumped numerical analysis

Konstantinos Gryllias, Eric Chatelet, Francesco Massi, Emmanuel Moulin

This paper investigates the concept of transferring / pumping vibroacoustic energy from an ambient acoustic field towards a secondary acoustic field by exploiting the dry contact friction nonlinearities. The secondary acoustic field could be used, for instance, as a reference signal in structural…

Optical properties of HgTe nanocrystals

Guy Allan, Christophe Delerue, Ali Al-Otaify, David J. Binks, Stephen V. Kershaw, Shuchi Gupta, Andrey L. Rogach

HgTe nanocrystals presently receive growing interest because the negative band gap in bulk HgTe enables tunability of the gap from the infrared to the near infrared in quantum dots thanks to the quantum confinement. Therefore we propose a tight-binding model of HgTe which gives an accurate band…

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…

Ferroelectrics based absorbing layers

Jianping Hao, Véronique Sadaune, Ludovic Burgnies, Didier Lippens

We show that ferroelectrics-based periodic structure made of BaSrTiO3 (BST) cubes, arrayed onto a metal plate with a thin dielectric spacer film exhibit a dramatic enhancement of absorbance with value close to unity. The enhancement is found around the Mie magnetic resonance of the Ferroelectrics…

All optical method for investigation of spin and charge transport in semiconductors : combination of spatially and time-resolved luminescence

Fabian Cadiz, Philippe Barate, D. Paget, Denis S Grebenkov, J.P. Korb, A.C.H. Rowe, Thierry Amand, S. Arscott, Emilien Peytavit

A new approach is demonstrated for investigating charge and spin diffusion as well as surface and bulk recombination in unpassivated doped semiconductors. This approach consists in using two complementary, conceptually related, techniques, which are time-resolved photoluminescence (TRPL) and…

Caractérisation par acoustique picoseconde des propriétés mécaniques du PZT déposé en couches minces pour des applications MEMS

Fabrice Casset

Les MEMS sont aujourd'hui une réalité économique et sont d'ores et déjà utilisés dans un grand nombre d'objets de notre quotidien. Ces composants peuvent utiliser un actionnement piézoélectrique, notamment à base de PZT déposé en couches minces, du fait de son fort coefficient…

Simulation of the metal-semiconductor-metal photodetector based on InGaAs for the photodetection at the wavelength 1.55 µm

M. El Besseghi, Abdelkader Aissat, Didier Decoster

In this paper we present the simulation of Metal-Semiconductor-Metal photodetector (MSM-PD) of interdigitated planar structure based on InAlAs/InGaAs adapted for photodetection at the wavelength 1.55 μm. We use the theoretical models to plot the variations of the dark current, the photocurrent, the…

Novel heterostructured Ge nanowires based on polytype transformation

Laetitia Vincent, Gilles Patriarche, Géraldine Hallais, Charles Renard, Cyrille Gardès, David Troadec, Daniel Bouchier

We report on a strain-induced phase transformation in Ge nanowires under external shear stresses. The resulted polytype heterostructure may have great potential for photonics and thermoelectric applications. ⟨111⟩-oriented Ge nanowires with standard diamond structure (3C) undergo a phase…
