Optimization and Comparison between the efficiency of GaNAsSb and GaInNAs single solar cells deposed on GaAs

Wafa Bellil, Abdelkader Aissat, Jean-Pierre Vilcot

In this work we study and optimize the single solar cell efficiency of GaNxAs1-x-ySby and Ga1-xInxNyAs1-y deposed on GaAs. The solar cells are simulated, in the aim to find the best concentration of nitrogen and antimony for GaNxAs1-x-ySby, and indium and nitrogen for Ga1-xInxNyAs1-y which gives us…

High Frequency Analysis and Small-Signal Modeling of AlGaN/GaN HEMTs with SiO2/SiN Passivation

Moujahed Gassoumi, Abdelhamid Helali, Malek Gassoumi, Christophe Gaquière, Hassen Maaref

AlGaN/GaN high electron mobility transistors (HEMTs) on Silicon substrates grown by molecular beam epitaxy have been investigated using small-signal microwave measurements, to see performance Radio-frequency of components. Passivation of HEMT devices SiO2/SiN a different pretreatment is used to…

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…

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)…

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…

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…

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…

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.…
