Opening of simultaneous photonic and phononic band gap in two-dimensional square lattice periodic structure

Driss Bria, B. Assouar, Mourad Oudich, Yan Pennec, Jerome O. Vasseur, Bahram Djafari-Rouhani

We discuss two points related to the simultaneous existence of phononic and photonic band gaps in a two-dimensional crystal constituted by a square array of holes drilled in a matrix. In a first part, using the case of a sapphire sample in the microwave range, we show that in addition to the…

High Gain and Fast Detection of Warfare Agents Using Back-Gated Silicon-Nanowired MOSFETs

Vikram Passi, Florent Ravaux, Emmanuel Dubois, Simon Clavaguera, Alexandre Carella, Caroline Celle, Jean-Pierre Simonato, Luca Silvestri, Susanna Reggiani, Dominique Vuillaume, Jean-Pierre Raskin

—The top-down fabrication of doped p-type silicon-nanowired (NW) arrays and their application as gas detectors is presented. After surface functionalization with 3-(4-ethynyl-benzyl)-1, 5, 7-trimethyl-3-azabicyclo [3.3.1] nonane-7-methanol molecules, the wires were subjected to an organophosphorous…

First AlN/GaN HEMTs power measurement at 18 GHz on silicon substrate

F Medjdoub, Malek Zegaoui, Damien Ducatteau, N. Rolland, Paul-Alain Rolland

AlN/GaN heterostructure is an ideal candidate to push the limits of microwave GaN-based devices owing to the maximum theoretical spontaneous and piezoelectric difference between the epitaxial AlN barrier and the underlying GaN layer. If the tricky growth conditions of this binary can be controlled…

Beyond 100 GHz AlN/GaN HEMTs on silicon substrate

F Medjdoub, Malek Zegaoui, N. Rolland

A report is presented on high-speed 100nm AlN/GaN high-electron-mobility transistors (HEMTs) grown on (111) high-resistive silicon substrate. The device delivers an extrinsic peak transconductance gm=530mS/mm, a maximum current of 1.74A/mm, and current gain and maximum oscillation cutoff…

Very low effective electromagnetic parameters lenses for the unlicensed 60 GHz band

Miguel Navarro-Cia, Miguel Beruete, Mario Sorolla, Tahsin Akalin, Nader Engheta

In this presentation advances on metallic lenses based on extreme electromagnetic parameters will be shown: either epsilon near zero or epsilon and mu near zero simultaneously. The former is generated by an array of continuous waveguides at cutoff, whereas the latter is composed of stacked…

Recent developments in amorphous sputterred ITO thin films acting as transparent front contact layer of CIGS solar cells for energy autonomous wireless microsystems

Thomas Aviles, C. Lethien, Malek Zegaoui, Jean-Pierre Vilcot, Floriane Leroy, Pascal Roussel, Nathalie Rolland, Paul-Alain Rolland

In this paper, we report on the study of electrical, optical and structural properties of RF sputtered Indium Tin Oxide (ITO) thin films at room temperature. These films are dedicated to act as front electrode of CIGS solar microcells and shall so compel with the electrical and optical criteria…
