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...

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...

Development of high-speed, patch-antenna intersubband photodetectors at 10.3um

Q. Lin, M Hakl, S Pirotta, R. Colombelli, W. Wan, H Li, J. Cao, Jean-Francois Lampin, Emilien Peytavit, S Barbieri

We present our work towards the development of high-speed, GaAs-AlGaAs multi-quantum wells photodetectors at 10.3m, based on two-dimensional arrays of patch-antenna resonators. First, the results of FDTD simulations will be presented that allowed to optimize the patch array geometry and fabricate...

Reservoir Computing for Sensing - an Experimental Approach

Dawid Przyczyna, Sébastien Pecqueur, Dominique Vuillaume, Konrad Szacilowski

The increasing popularity of machine learning solutions puts increasing restrictions on this field if it is to penetrate more aspects of life. In particular, energy efficiency and speed of operation is crucial, inter alia in portable medical devices. The Reservoir Computing (RC) paradigm poses as a...

An Integrated Photoacoustic Terahertz Gas Sensor

Mattias Verstuyft, Elias Akiki, Benjamin Walter, Marc Faucher, Mathias Vanwolleghem, Bart Kuyken

An on-chip gas detector that transduces absorbed terahertz light to a mechanical motion using photoacoustics is proposed. The silicon chip confines light in an optical cavity, wherein an acousto-mechanical cavity is housed. The concentration of a trace gas can be determined from the amplitude of a...
