High Mobility InAs/GaSb Quantum Well and in-Plane Core-Shell Nanostructures Grown on Highly Mismatched Substrates

Wijden Khelifi, Christophe Coinon, Maxime Berthe, David Troadec, Gilles Patriarche, B. Grandidier, L. Desplanque

We present the growth of InAs based heterostructures by molecular beam epitaxy on highly mismatched GaAs and InP substrates. We particularly investigate the protection of the InAs channel both with respect to the interface dislocation network arising at the mismatched interface using a GaSb...

Magnetization rotation-based polarization control of spintronic terahertz emitter

Pierre Kolejak, Geoffrey Lezier, Kamil Postava, Jean-Francois Lampin, Nicolas Tiercelin, Mathias Vanwolleghem

Recently, the terahertz family of sources increased by newly-developed terahertz spintronic emitter (STE), which competes with the traditional in many ways. This30THz-broadband gapless source is versatile due to its low-cost, easy implementation, frequency-independent excitation, and...

First attempts of WSe2 growth on GaP(111)B substrates by MBE

N. Chapuis, Christophe Coinon, D. Deresmes, G. Patriarche, D. Vignaud, X. Wallart

Few layers WSe2 are grown on GaP(111)B surfaces passivated by selenium. The layers remains 2D at low growth temperature (Tg = 200-250°C) while exhibiting the formation of the metastable 1T’ phase. Medium growth temperatures (400-550°C) lead to a poor crystalline surface quality. In both cases,...

InSb thin films and selective area MBE grown nanostructures on InP(111)B substrate

Wijden Khelifi, Pierre Capiod, Christophe Coinon, Maxime Berthe, X. Wallart, B. Grandidier, L. Desplanque

The growth of InSb by molecular beam epitaxy on InP(111) substrate is investigated. We observe that a very large Sb/In flux ratio promotes the spreading of InSb, leading a rapid coalescence of initial 2D InSb islands and forming a smooth InSb layer after 100nm deposition. This growth mode is used...

Probing the Electrochemical Li Insertion–Extraction Mechanism in Sputtered LiNi0.5Mn1.5O4 Thin Film Cathode for Li‐Ion Microbattery

Ankush Bhatia, Clement Leviel, Maxime Hallot, Jean Pierre Pereira-Ramos, Christophe Lethien, Pascal Roussel, Rita Baddour-Hadjean

Due to its great theoretical capacity (147 mAh g−1) and high operating potential (4.7 V vs Li+/Li), Co-free spinel LiNi0.5Mn1.5O4 (LNMO) is one of the most promising thin film cathodes allowing designing Li-ion micro-batteries with a high specific energy. In this work, the Li extraction–insertion...

Understanding the Effect of Ni-Substitution on the Oxygen Evolution Reaction of (100) IrO 2 Surfaces

Gaëtan Buvat, Mohammad Eslamibidgoli, Tianjun Zhang, Sagar Prabhudev, Azza Hadj Youssef, Andreas Ruediger, Sébastien Garbarino, Gianluigi Botton, Peng Zhang, Michael Eikerling, Daniel Guay

The electrolysis process of water is impeded by the slow kinetics of the oxygen evolution reaction (OER). While iridium oxide (IrO2) is considered one of the most efficient metal catalysts for the OER, the adsorption of the OER intermediates at the IrO2 surface is not optimal, the *OH intermediate...

Improvement of emotion recognition from facial images using deep learning and early stopping cross validation

Mohamed Bentoumi, Mohamed Daoud, Mohamed Benaouali, Abdelmalik Taleb-Ahmed

Inthis paper, we present a new approach for emotion recognition from facial images. The proposed method is based on the association of a pretrained convolutional neural network (CNN) model (VGG16, ResNet50) with a multilayer perceptron (MLP) classifier. The pretrained CNN model is used as a feature...
