Love waves dispersion by phononic pillars for nano-particle mass sensing

Jérémy Bonhomme, Mourad Oudich, Bahram Djafari-Rouhani, Frédéric Sarry, Yan Pennec, B. Bonello, Denis Beyssen, P. Charette

We present a design of a pillared phononic crystal based structure for Love wave manipulation to achieve high mass sensitivity. The structure is made of phononic micro-pillars constructed by stacking tungsten and SiO2 layers, distributed on a substrate designed for Love wave propagation. The…

Electron Beam Curing of Monomer/Liquid Crystal Blends

Mohammed Bouchakour, Yazid Derouiche, Zohra Bouberka, Christophe Beyens, Philippe Supiot, Frédéric Dubois, Farid Riahi, Ulrich Maschke

This chapter focuses on a comparison of two polymerization/crosslinking methods to produce polymer/liquid crystal (LC) systems: rapid UV-visible irradiation and high voltage accelerated electron beams (EB), with comparable exposure times. The comparison was performed in terms of some physical…

On evaporation via an inclined rotating circular lift-off shadow or stencil mask

S. Arscott

A mathematical model is developed to calculate the topography of a mesa obtained by evaporation of matter via inclined rotating lift-off shadow masking. Two types of masking are considered: a circular mask and a cylindrical mask-the latter involves sidewall deposition. The model is able to predict…

Design and Implementation of Ternary Logic Integrated Circuits by Using Novel Two-Dimensional Materials

Mingqiang Huang, Xingli Wang, Guangchao Zhao, Philippe Coquet, Bengkang Tay

With the approaching end of Moore’s Law (that the number of transistors in a dense integrated circuit doubles every two years), the logic data density in modern binary digital integrated circuits can hardly be further improved due to the physical limitation. In this aspect, ternary logic (0, 1, 2)…

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…

An autonomous low-power management system for energy harvesting from a miniaturized spherical piezoelectric transducer

Daher Diab, Fabrice Lefebvre, Georges Nassar, Nikolay Smagin, Samih Isber, Fawaz El Omar, Adnan Naja

A new spherical vibrational energy harvesting device with an additional low power management circuit for optimizing the power transfer from the mechanical vibrations to a storage capacitor is presented. The device is devoted to underwater wireless sensor network applications due to its broadband…

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…
