Modeling of access resistances and channel temperature estimation for GaN HEMT

Shariful Islam, Mohammad Abdul Alim, Abu Zahed Chowdhury, Christophe Gaquière

Accurate prediction of resistances at the transistor’s access zone and their temperature dependency are very important, since the current flow to the device depends on that region. In this paper, we have modeled the access resistances and have verified their temperature dependency with the…

Non-Hermitian skin effect in a phononic beam based on piezoelectric feedback control

Yabin Jin, Wenxin Zhong, Runcheng Cai, Xiaoying Zhuang, Yan Pennec, Bahram Djafari-Rouhani

Non-Hermitian systems have gained a great deal of interest in various wave problems due their ability of exhibiting unprecedented phenomena such as invisibility, cloaking, enhanced sensing, or the skin effect. The latter manifests itself by the localization of all bulk modes in a specific frequency…

Electro-Acoustic Properties of Scandium-Doped Aluminum Nitride (Sc_xAl_1-xN) Material and its Application to Phononic Crystal-Coupled SAW Devices

Fahima Arab, Fares Kanouni, Rafik Serhane, Yan Pennec, Zafer Özer, Khaled Bouamama

Within the framework of the Density Functional Theory, the elastic, dielectric, and piezoelectric coefficients of w-ScxAl1−xN material were investigated for scandium (Sc) concentrations x = 0 to 0.375. The electro-acoustic properties are used to investigate the frequency response of the SAW delay…

Elaboration and characterization of porous ultrathin gold films grown by ion beam assisted deposition

Abdelhanin Aassime, Marc Duquennoy, Frédéric Hamouda, Tahar Kadi, Frédéric Mahut, Mohammadi Ouaftouh

The growth of ultrathin gold layers on a silicon substrate is performed with an unconventional ion beam assisted deposition. In this setup, evaporated gold flow and ion beam flux are perpendicular. 5 and 10 nm thick gold were deposited on tilted samples with the assistance of an argon ion beam at…

Application of Complex Geophysical Methods for the Detection of Unconsolidated Zones in Flood Dikes

Tomisław Gołębiowski, Bogdan Piwakowski, Michał Ćwiklik

The flood levees in the vicinity of Krakow city (Poland) are, in some places, over 100 years old. Thereupon, in the flood dike, and its subsoil, can appear unconsolidated zones, which, during the flood stage, can be a simple way of water flow and/or even can be the place where the levee body will…

Face Sketch Synthesis using Generative Adversarial Networks

Mahfoud Sami, Daamouche Abdelhamid, Bengherabi Messaoud, Boutellaa Elhocine, Abdenour Hadid

Face Sketch Synthesis is crucial for a wide range of practical applications, including digital entertainment and law enforcement. Recent approaches based on Generative Adversarial Networks (GANs) have shown compelling results in image-to-image translation as well as face photo-sketch synthesis.…

Catch and release strategy of matrix metalloprotease aptamers via thiol–disulfide exchange reaction on a graphene based electrochemical sensor

Vladyslav Mishyn, Merve Aslan, Adrien Hugo, Teresa Rodrigues, Henri Happy, Rana Sanyal, Wolfgang Knoll, Florence Baudoux, Vincent Bouchiat, Rostyslav Bilyy, Rabah Boukherroub, Amitav Sanyal, Sabine Szunerits

Matrix metalloproteases (MMP) are a large family of proteases, which synergistically degrade abundant extracellular matrix and play an essential role in tissue degradation and remodelling. Sensing of MMP levels, notably the pro- and activated matrix metalloproteinases (MMP-2 and MMP-9), would…

Plasmonic Tamm states in periodic stubbed MIM waveguides: analytical and numerical study

Yamina Rezzouk, Madiha Amrani, Soufyane Khattou, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We investigate both analytically and numerically the existence of localized surface modes, the so-called plasmonic Tamm states (PTSs), in a new and versatile platform based on a periodic array of metal-insulator-metal (MIM) stubs grafted along a MIM waveguide. By considering a semi-infinite…

Transport Properties of Methyl-Terminated Germanane Microcrystallites

Davide Sciacca, Maxime Berthe, Bradley Ryan, Nemanja Peric, D. Deresmes, Louis Biadala, Christophe Boyaval, Ahmed Addad, Ophélie Lancry, Raghda Makarem, Sébastien Legendre, Didier Hocrelle, Matthew Panthani, Geoffroy Prévot, Emmanuel Lhuillier, Pascale Diener, B. Grandidier

Germanane is a two-dimensional material consisting of stacks of atomically thin germanium sheets. It’s easy and low-cost synthesis holds promise for the development of atomic-scale devices. However, to become an electronic-grade material, high-quality layered crystals with good chemical purity and…

A comparison of pad metallization in miniaturized microfabricated silicon microcantilever-based wafer probes for low contact force low skate on-wafer measurements

Khadim Daffe, Jaouad Marzouk, Christophe Boyaval, Gilles Dambrine, Kamel Haddadi, S. Arscott

Miniaturized, microfabricated microelectromechanical systems (MEMS)-based wafer probes are used here to evaluate different contact pad metallization at low tip forces (<mN) and low skate on the on-wafer pads. The target application is low force RF probes for on-wafer measurements which cause…
