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…

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…

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…

Giant, Anomalous Piezoimpedance in Silicon-on-insulator

H. Li, C.T.K. Lew, B.C. Johnson, J.C. Mccallum, S. Arscott, A.C.H. Rowe

A giant, anomalous piezoresponse of fully depleted silicon-on-insulator devices under mechanical stress is demonstrated by impedance spectroscopy. This piezoresponse strongly depends on the measurement frequency, ω, and consists of both a piezoresistance (PZR) and a piezocapacitance, whose maximum…

Low-power phonon lasing through position-modulated Kerr-type nonlinearity

P. Djorwe, Yan Pennec, Bahram Djafari-Rouhani

We demonstrate low-power amplification process in cavity optomechanics (COM). This operation is based on the nonlinear position-modulated self-Kerr interaction. Owing to this nonlinear term, the effective coupling highly scales with the photon number, resulting in a giant enhancement of the…

Simulation and experimental study of GaAs substrate thermal conductivity using 3-omega method

A. A. Guermoudi, Pierre-Yves Cresson, A. Ouldabbes, T. Lasri

GaAs is a widely used III-V semiconductor compound in microelectronics. Since the 90's, a growing interest is observed for its larger integration in electronics industry (micro and nano electronics) and solar in cells. Therefore, new characterization needs are emerging to address this kind of…
