Transmorphic epitaxial growth of AlN nucleation layers on SiC substrates for high-breakdown thin GaN transistors

Jun Lu, Jr-Tai Chen, Martin Dahlqvist, Riad Kabouche, F Medjdoub, Johanna Rosen, Olof Kordina, Lars Hultman

ABSTRACT Interfaces containing misfit dislocations deteriorate electronic properties of heteroepitaxial wide bandgap III-nitride semiconductors grown on foreign substrates, as a result of lattice and thermal expansion mismatches and incompatible chemical bonding. We report grain-boundary-free AlN...

Chapter 7 - Two-dimensional magnonic crystals

L. Dobrzynski, Housni Al-Wahsh, Abdellatif Akjouj, Yan Pennec, Bahram Djafari-Rouhani

This chapter presents a short tutorial introduction to the theoretical investigations of two-dimensional inhomogeneous magnetic media. Simple examples are presented for the calculation of the spin-wave spectra of two-dimensional composite materials consisting of periodic square arrays of parallel...

Towards all-solution-processed top-illuminated flexible organic solar cells using ultrathin Ag-modified graphite-coated poly(ethylene terephthalate) substrates

Shuanglong Wang, Yi Zhao, Hong Lian, Cuiyun Peng, Xuyong Yang, Yulai Gao, Yan Peng, Weixia Lan, Omar Ibrahim Elmi, Didier Stiévenard, Bin Wei, Furong Zhu, Tao Xu

All-solution-processed flexible organic solar cells (FOSCs) with high power conversion efficiency (PCE) are the prerequisite for application in low-cost, large-area, flexible, photovoltaic devices. In this work, high-performance, top-illuminated FOSCs using ultrathin Ag-modified graphite-coated...

Modulation of localized surface plasmon resonances of a silver nanoparticle array upon the presence of MoS2 coatings or underlying thin films

Mohamed El Barghouti, Abdellah Mir, Abdellatif Akjouj, Sabine Szunerits

There has been recently a growing interest in studying light-matter coupling using supported metallic nanostructures arranged into periodic arrays. The influence on the layer thickness of two-dimensional materials such as molybdenum disulfide MoS2 on the plasmonic behaviour of these arrays has...

Numerical Modelling of Vibration Characteristics of a Partially Metallized Micro Electromechanical System Resonator Disc

Ismail Naciri, Abdessamad Rguiti, Lahoucine Elmaimouni, Jean-Etienne Lefebvre, Faniry Emilson Ratolojanahary, J. G. Yu, Youssef Belkassmi, Ali El Moussati

In this paper, we report an extension of a polynomial and numerical vibrational characterization of an annular piezoelectric disc resonator partially covered with electrodes. The three governing partial differential equations of motion are solved to provide the frequency response of the...

Mesure indirecte des performances de LLR approché

Yasser Mestrah, Anne Savard, Alban Goupil, Guillaume Gelle, Laurent Clavier

Les réseaux sans fils sont de plus en plus denses et hétérogènes, entraînant l’accroissement très significatif de l’impact des interférences. De nombreux travaux ont montré la nature impulsive de cette interférence et la nécessité de modifier le calcul de la vraisemblance nécessaire au décodage....

Topological valley, pseudospin, and pseudospin-valley protected edge states in symmetric pillared phononic crystals

Wei Wang​, Bernard Bonello, Bahram Djafari-Rouhani, Yan Pennec

We present a symmetric double-sided pillared phononic crystal (PPnC) where either quantum spin Hall effect (QSHE) or quantum valley Hall effect (QVHE) is emulated by solely imposing different perturbations to the geometry. When occurring at the deep subwavelength scale, the valley-polarized edge...
