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…

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…

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)…

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…

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…
