A study of DC and RF transconductance for different technologies of HEMT at low and high temperatures

Mohammad Abdul Alim, Anwar Jarndal, Christophe Gaquière, Giovanni Crupi

AbstractWe report on the measured effects of temperature on the DC and RF transconductance for several important HEMT technologies. Six different HEMT transistors were evaluated. Single- and double-heterojunction HEMTs, GaAs and GaN materials, virgin and multi-layer pHEMTs, and matched and...

High-Q Resonant Modes in Periodic Stubbed Structure

Yamina Rezzouk, Mohamed El Ghafiani, Soufyane Khattou, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) have unique properties and significant applications in photonics. In this paper, we show analytically and experimentally the existence of (N−1) BICs (multi-BICs) in the flat band of a periodic photonic comb made of N stubs of length d2 separated by segments of...

Improvement of Silicon Nanowire-Based Photovoltaic Solar Cell with the Integration of CIGS Quantum Wells

Meriem Safi, Abdelkader Aissat, Houcine Guesmi, Jean-Pierre Vilcot

The present work focuses on the modeling and simulation of a new photovoltaic solar cell based on a CIGS/Si nanowire. The study of the effect of inserting quantum wells in a nanowire structure for different characteristic parameters has been done to evaluate the potential of the confinement...

Zak Phase and Topological Tamm States Between Two Photonic Comb Structures

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

We investigate the existence of Tamm states at the interface between two one-dimensional (1D) photonic crystals (PCs) through an analysis of local density of states (LDOS) using the Green’s function method. The PCs are made of a comb-like structure consisting of stubs grafted periodically along a...

Behavior of conducting polymer-based micro-actuators under a DC voltage

L. Seurre, H. Aréna, Sofiane Ghenna, Caroline Soyer, Sébastien Grondel, Cedric Plesse, G.T.M. Nguyen, Eric Cattan, Frédéric Vidal

Conducting polymer-based micro-actuators are of great interest in soft MEMS as they exhibit large strains and forces in response to electrical stimulation. To date, these micro-actuators have very often been characterized by applying low frequency voltage to extract the electromechanical...

Study of reaction-diffusion controlled mass transport in stopped-flow fluidics for spatiotemporal multiplexing

Marcel Tintelott, Pradnya Gharpure, Yannick Coffinier, Xuan Thang Vu, Alexis Vlandas, Sven Ingebrandt, Vivek Pachauri

Integration of biochemical reaction networks (BRNs) with biosensor platforms has emerged as a technological niche overcoming challenges related to the loss of sensitivity and selectivity in biological media. Optimal operation of BRNs in microfluidics requires control over reaction-diffusion...

High-Density Single Antibody Electrochemical Nanoarrays

Khalil Chennit, Yannick Coffinier, Shuo Li, Nicolas Clément, Agnès Anne, Arnaud Chovin, Christophe Demaille

The fabrication and electrochemical interrogation of very high density single-antibody nanoarrays is reported. Gold nanodots, 15 nm in diameter, arranged in large (cm2) square arrays with a pitch of 200 nm, are used as carriers for primary antibodies (Immunoglobulin G, IgGs), further recognized by...
