High Efficiency AlN/GaN HEMTs for Q-Band Applications with an Improved Thermal Dissipation

Riad Kabouche, Romain Pecheux, Kathia Harrouche, Etienne Okada, F Medjdoub, Joff Derluyn, Stefan Degroote, Marianne Germain, Filip Gucmann, Callum Middleton, James W Pomeroy, Martin Kuball

In this paper, we demonstrate Q-band power performance of carbon doped AlN/GaN high electron mobility transistors (HEMTs) using a deep sub-micrometer gate length (120 nm). With a maximum drain current density ID of 1.5 A/mm associated to a high electron confinement and an extrinsic transconductance…

Rainbow guiding of the lowest-order antisymmetric Lamb mode in phononic crystal plate

Jinfeng Zhao, Weitao Yuan, Bernard Bonello, Bahram Djafari-Rouhani, Yongdong P Pan, Zheng Zhong

The modern acoustic circuits have experienced significant progress with the development of artificial structures, including phononic crystals, metamaterials or metasurfaces. Among the most intensive topics, the reconfigurable acoustic guides are achieved through several mechanisms. In this work, we…

“Click” Chemistry on Gold Electrodes Modified with Reduced Graphene Oxide by Electrophoretic Deposition

Vladyslav Mishyn, Patrik Aspermair, Yann R. Leroux, Henri Happy, Wolfgang Knoll, Rabah Boukherroub, Sabine Szunerits

The coating of electrical interfaces with reduced graphene oxide (rGO) films and their subsequent chemical modification are essential steps in the fabrication of graphene-based sensing platforms. In this work, electrophoretic deposition (EPD) of graphene oxide at 2.5 V for 300 s followed by vapor…

Elaboration of nanomagnet arrays: organization and magnetic properties of mass-selected FePt nanoparticles deposited on epitaxially grown graphene on Ir(111)

Pierre Capiod, Laurent Bardotti, Alexandre Tamion, Olivier Boisron, Clément Albin, Veronique Dupuis, Gilles Renaud, Philippe Ohresser, Florent Tournus

The moiré pattern created by the epitaxy of a graphene sheet on an iridium substrate can be used as a template for the growth of 2D atomic or cluster arrays. We observed for the first time a coherent organization of hard magnetic preformed FePt nanoparticles on the 2D lattice of graphene/Ir(111).…

A Sub-35 pW Axon-Hillock artificial neuron circuit

Francois Danneville, Christophe Loyez, K. Carpentier, I. Sourikopoulos, E. Mercier, A. Cappy

Artificial Intelligence (AI) applications are developing at a high rate, facing soon a tremendous energy challenge. In this context, the original Axon-Hillock (AH) Artificial Neuron (AN) has been optimized to achieve ultra-low power (ULP) consumption. The membrane capacitance was taken out, and in…

Sound absorption by green walls at normal incidence: physical analysis and optimization

Emmanuel Attal, Nicolas Côté, Takafumi Shimizu, Bertrand Dubus

Sound absorption by different green wall systems at normal incidence is investigated between 100 and 1000 Hz. Measurements are conducted in an impedance tube in order to estimate the effective acoustic properties of plants and soils. Using these properties, the transfer matrix method is employed to…

Terahertz plasmon-induced transparency and absorption in compact graphene-based coupled nanoribbons

Adnane Noual, Madiha Amrani, El Houssaine El Boudouti, Yan Pennec, Bahram Djafari-Rouhani

We investigate theoretically and numerically the possibility of realizing plasmon-induced transparency (PIT) and plasmon-induced absorption (PIA) in a novel compact graphene-based nanostructure. The main graphene bus waveguide is coupled to two graphene nanoribbons (GNRs). The PIT effect is…

Thermal influence on S₂₂ kink behavior of a 0.15 μm gate length AlGaN/GaN/SiC HEMT for microwave applications

Mohammad A Alim, Ali A Rezazadeh, Christophe Gaquière, Giovanni Crupi

Abstract Thermal influence on S22 kink behavior has been carried out on a 0.15 μm gate length AlGaN/GaN/SiC high electron mobility transistor over a wide range of temperature. The size and the shape of the S22 kink effect (KE) in terms of biasing and temperature have been evaluated. The main…
