Multilayer modeling of thermoacoustic sound generation for thermophone analysis and design

Pierre Guiraud, Stefano Giordano, Olivier Bou Matar, Philippe Pernod, Raphael Lardat

A general model for thermoacoustic sound generation, based on the classical conservation laws of mass, momentum and energy, is presented and adopted to analyze different thermophone structures. This model is able to describe an arbitrary multilayered (or laminated) system composed of both solid and…

Improvement in carrier dynamics in In_xGa_1-xN/GaN multi-quantum well for solar cell applications

Abdelkader Aissat, Jean-Pierre Vilcot

In this work, we have studied and simulated nanostructures to improve the solar cell efficiency. The idea of this study is to insert multi-quantum wells in the structure of a solar cell (MQWSC). The electric field, recombination, and the photogeneration rates of charge carriers in QWSC influence…

Magnetic Interactions on Oxide Ferromagnet/Ferromagnetic Intermetallide Interface

G. Ovsyannikov, V. Demidov, T. Shaikhulov, A. Klimov, Nicolas Tiercelin, Philippe Pernod, S. Nikitov

The magnetic properties of heterostructures consisting of two films are studied. The upper layer involves rare-earth intermetallic nanostructured superlattices consisting of exchange-coupled layers (TbCo 2 /FeCo) n (TCFC), and the lower layer includes either epitaxial manganite La 0.7 Sr 0.3 MnO 3…

Conductivity of Manganite Films under the Action of Tension Caused by the Deformation of Substrate

G. Ovsyannikov, T. Shaikhulov, V. Shakhunov, A. Klimov, V. Preobrazhenskii, Nicolas Tiercelin, Philippe Pernod

The electron transport properties of strained thin La 0.7 Ba 0.3 MnO 3 (LBMO) epitaxial films are studied. Films 40-100 nm in thickness were prepared by laser ablation at a temperature T = 700-800°C in pure oxygen atmosphere of 0.3-1 mBar. Ferroelectric crystal substrates (011)0.79PbMg 1/3 Nb 2/3 O…

Device for broadband THz spectroscopy of 1-nL-volume samples

Sergey Mitryukovskiy, Melanie Lavancier, Flavie Braud, Theo Hannotte, Emmanuel Dubois, Jean-Francois Lampin, Romain Peretti

We report on our recent progress in the development of a device for light-matter interaction enhancement in the full terahertz range for precise spectroscopy of minor-volume samples. The efficient confinement of a broadband terahertz pulse to a few-nL-volume was achieved, opening new perspectives…

Chalcogenide glasses as a playground for the application of first-principles molecular dynamics to disordered materials

Guido Ori, Assil Bouzid, Évelyne Martin, Carlo Massobrio, Sébastien Le Roux, Mauro Boero

An overview of the major first-principles methods used to simulate condensed phases is presented, with special emphasis on chalcogenide glasses. The scope of this review article is to offer a survey of fundamental algorithms and techniques, accompanied by a few recent examples particularly…

Combined UTC-PD integrated on-chip THz near field microscopy with coupled planar Goubau lines

Tahsin Akalin, Abdallah Chahadih, Abbas Ghaddar, Ibrahim Tirer

In most of the cases for terahertz near field microscopy, a free space propagating electromagnetic wave interacts with a small tip placed above the sample. In our original approach, we use a guided way to bring the terahertz wave and to improve the interaction efficiency with the sample. The idea…
