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…

High-definition television transmission at 600 GHz combining THz photonics hotspot and high-sensitivity heterodyne receiver

Guillaume Ducournau, Fabio Pavanello, Alexandre Beck, L. Tohme, S. Blin, P. Nouvel, Emilien Peytavit, Mohamed Zaknoune, P. Szriftgiser, Jean-Francois Lampin

A 600 GHz data transmission using the combination of a photonic emission using a uni-travelling carrier photodiode and an electronic detection is investigated. A high-definition television transmission at this carrier frequency with a very low power at the receiver is reported. Only 10 nW of…

Parametric study of self-forming ZnO nanowall network with honeycomb structure by pulsed laser deposition

Basma El Zein, S. Boulfrad, G.E. Jabbour, El Hadj Dogheche

The successful synthesis of catalyst free zinc oxide (ZnO) Nanowall networks with honeycomb like struc-ture by Pulsed Laser Deposition (PLD) is demonstrated in this paper. The synthesis was conducted directlyon Silicon (Si) (1 0 0) and Glass-ITO substrates without the intermediate of metal catalyst…

Polarization properties of specular and dense multipath components in a large industrial hall

Isabelle Vin, Davy Gaillot, Emmeric Tanghe, Wout Joseph, Pierre Laly, M. Lienard, Luc Martens

This paper presents a comprehensive analysis of the polarization characteristics of specular and dense multipath components in a large industrial hall, based on frequency-domain channel sounding experiments at 1.3 GHz. The RiMAX maximum-likelihood estimator is used to extract the full-polarimetric…

Dirac cones, topological edge states, and nontrivial flat bands in two-dimensional semiconductors with a honeycomb nanogeometry

Efterpi Kalesaki, Christophe Delerue, Cristiane Morais Smith, Wouter Beugeling, Guy Allan, Daniel Vanmaekelbergh

We study theoretically two-dimensional single-crystalline sheets of semiconductors that form a honeycomb lattice with a period below 10 nm. These systems could combine the usual semiconductor properties with Dirac bands. Using atomistic tight-binding calculations, we show that both the atomic…

Current-voltage characteristics of (Mo/Au)/AlGaN/GaN/Si Schottky diodes

H. Mosbahi, M. Charfeddine, M. Gassoumi, Christophe Gaquière, M.A. Zaidi, H. Maaref

The AlGaN/GaN high electron mobility transistors (HEMTs) is a promising candidate for microwave applications due to its high power and high temperature. owing to their large and direct band gap, as well as favorable transport properties. Moreover, III-V nitrides could be suitable for the emitters…

Improved efficiency by the effect of strain on the structure of a solar cell based on GaInP/GaAs

Abdelkader Aissat, Rachid Bestam, Jean-Pierre Vilcot

This work is aimed at the study of GaInP-based photovoltaic cell. The effects of In content, lattice parameter mismatch and thickness of the SiO2 insulating layer on the characteristics and efficiency of the GaInP structure were investigated. We noticed that for higher In concentrations, the band…

Approach-to-equilibrium molecular dynamics for thermal conductivies and boundary conductances

Pier Luca Palla, Evelyne Lampin, Pierre-Arnaud Francioso, Fabrizio Cleri

Thermal transport is simulated at the atomic scale by approach-to-equilibrium molecular dynamics simulations (AEMD) [1]. In this method, a hot and a cold regions are delimited, before the approach-to-equilibrium is simulated by releasing the thermal constraint. The temperature difference between…
