Métasurface absorbante parfaite à base de cubes ferroélectriques distribués aléatoirement

Véronique Sadaune, Ludovic Burgnies, Eric Lheurette, Jianping Hao, Didier Lippens

L'utilisation d'une structure périodique de cubes de BaSrTiO3 interfacée avec une surface métallique par un fin film diélectrique permet d'obtenir une absorption proche de 100% à la fréquence de résonance de Mie magnétique. Cette absorption reste élevée pour un angle d'incidence...

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...

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...

Optomechanical interactions in two-dimensional Si and GaAs phoXonic cavities

Said El-Jallal, M. Oudich, Yan Pennec, Bahram Djafari-Rouhani, A. Makhoute, Quentin Rolland, Samuel Dupont, Joseph Gazalet

We investigate theoretically the optomechanical interactions inside cavities created in two-dimensional infinite phoXonic crystals constituted by a square array of holes in silicon (Si) and gallium arsenide (GaAs) matrices. The cavity is simply obtained by removing one hole in the perfect crystal....

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 carbon nanotube thin films in subterahertz frequency regime

Sujitha Puthukodan, Ehsan Dadrasnia, V.K.T. Vinod, Horacio Lamela Rivera, Guillaume Ducournau, Jean-Francois Lampin

Multiwalled carbon nanotube (MWCNT) thin films deposited on fused quartz substrates are characterized by continuous wave subterahertz free space technique using a vector network analyzer (VNA). The scattering (S) parameters are measured by a VNA in the frequency range of 220-325 GHz (G-band) and...

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...
