An advanced ageing methodology for robustness assessment of normally-off AlGaN/GaN HEMT

F. Albany, A. Curutchet, N. Labat, F. Lecourt, E. Walasiak, H. Maher, Y. Cordier, N. Defrance, N. Malbert

The semi-on-state reliability of normally-off AlGaN/GaN high electron mobility transistor fabricated by fluorine ion plasma implantation technology is reported, focusing on an advanced dc step-stress methodology. By inserting a non-stressful fixed-bias step between each stress step, a reliable in-…

Bias-dependence of surface charge at low temperature in GaN self-switching diodes

E. Perez-Martin, I. Iniguez-De-La-Torre, T. Gonzalez, Christophe Gaquière, J. Mateos

In this work, with the help of a semi-classical two-dimensional Monte Carlo (MC) simulator, we study the DC current-voltage curves of Self-Switching Diodes (SSDs) fabricated on an AlGaN/GaN heterostructure from 100 K up to room temperature. Due to the very narrow channel of the SSDs, the presence…

3 - Path states

L. Dobrzynski, Housni Al Wahsh, Abdellatif Akjouj, El Houssaine El Boudouti, Bahram Djafari-Rouhani, Cécile Ghouila-Houri, Abdelkrim Talbi, Gaëtan Lévêque

Any open and closed loop eigenfunction has zero motion space points, called here robust zeros. Any such zero is robust because its eigenstate cannot be activated by any action applied on it. Indeed, such zero space positions remain unaffected when the loop is interfaced with its outside world only…

1 - Open loop

L. Dobrzynski, Housni Al Wahsh, Abdellatif Akjouj, El Houssaine El Boudouti, Cécile Ghouila-Houri, Abdelkrim Talbi, Gaëtan Lévêque, Bahram Djafari-Rouhani, Yan Pennec, Yabin Jin

Networks can be constructed out of finite open loops. Open loops are guides such that their one-dimensional properties may be considered independent of the open loop shape and radius. Their response function is derived from that of infinite open loops. A general definition of eigenstates is also…

Thermoacoustic wave generation in multilayered thermophones with cylindrical and spherical geometries

Pierre Guiraud, Stefano Giordano, Olivier Bou Matar, Philippe Pernod, Raphael Lardat

A thermoacoustic sound generation model, based on the classical balance equations of the continuum mechanics, is here developed for the cylindrical and the spherical thermoacoustic wave generation. In both geometries, the model considers an arbitrary multilayered structure, where each layer can be…

17 - Interface Response Function in Layered Photonic Materials

Abdellatif Akjouj, L. Dobrzynski, Gaëtan Lévêque, El Houssaine El Boudouti

The interface response theory was presented for any composite material in discrete, continuous, and mixed (partly discrete \textendash partly continuous) spaces (see Chapter 1 of Phononics in Interface Transmission Tutorial Book Series). The aim of this chapter is to show how this theory can be…

14 - One-Dimensional Photonic Waveguide for Filtering and Demultiplexing

Yan Pennec, Bahram Djafari-Rouhani, Abdellatif Akjouj, El Houssaine El Boudouti, Gaëtan Lévêque, L. Dobrzynski

In this chapter, we review numerical simulations of light propagation in one-dimensional photonic semiconductor optical waveguides coupled to one or several lateral stubs. In the presence of one stub, we show that the transmission spectrum contains several narrow dips, provided that the boundaries…

On chip MnO₂-based 3D micro-supercapacitors with ultra-high areal energy density

Botayna Bounor, Bouchra Asbani, Camille Douard, Frédéric Favier, Thierry Brousse, Christophe Lethien

In the near future, Internet of Things will be widely deployed all over the connected world. Powering will be crucial for miniaturized electronic devices requiring fast charging, high energy density and long term-durability. 3D micro-supercapacitors are an attractive energy storage solution at the…

A weighted exponential discriminant analysis through side-information for face and kinship verification using statistical binarized image features

Oualid Laiadi, Abdelmalik Ouamane, Abdelhamid Benakcha, Abdelmalik Taleb-Ahmed, Abdenour Hadid

Side-information based exponential discriminant analysis (SIEDA) is more efficient than side-information based linear discriminant analysis (SILDA) in computing the discriminant vectors because it maximizes the Fisher criterion function. In this paper, we develop a novel criterion, named side-…
