15 - Silicon Nanowires and Nanopillars for Photovoltaic

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

We present simulations on both the optical properties and the efficiency of nanowires (NWs), nanopillars (NPs) and nanocones (NCs) silicon-based solar cells, together with measurements on their associated optical absorption. We address the calculation using Green's function formalism and…

20 - Omnidirectional Bandgaps and Selective Transmission in Layered Photonic Crystals

Abdellatif Akjouj, El Houssaine El Boudouti, L. Dobrzynski, Bahram Djafari-Rouhani

It has been shown that a one-dimensional periodic structure such as a layered photonic crystal can exhibit the property of omnidirectional reflection, which means that any incident wave launched from the vacuum (or from a substrate) will undergo a total reflection at the layered photonic crystal…

22 - Superluminal, Negative Delay Times and Selective Transmission in Isotropic-Anisotropic Layered Media

El Houssaine El Boudouti, Bahram Djafari-Rouhani, Abdellatif Akjouj, L. Dobrzynski

In this chapter, we investigate the possibility of superluminal and negative delay times for electromagnetic wave propagation in a linear and passive periodic structure consisting of alternating isotropic and anisotropic media. These phenomena are due to the birefringence of the anisotropic layers…

[Invited] SOI-based opto-mechanical Terahertz bolometer operating at room temperature with microsecond response time

K. Froberger, Marc Faucher, B. Walter, M. Lavancier, Romain Peretti, Jean-Francois Lampin, Guillaume Ducournau, S Barbieri

We report the operation of a Terahertz (THz) detector exploiting the bi-material effect to resonantly excite a cantilever (CL) of micrometric size. The detector is fabricated on a SOI substrate and coupling to the incident THz radiation is obtained using two coupled aluminum half-dipole antennas.…

Asymmetric micro-supercapacitors based on electrodeposited Ruo2 and sputtered VN films

Bouchra Asbani, Kevin Robert, Pascal Roussel, Thierry Brousse, Christophe Lethien

Research on micro-supercapacitors remains one of the most important activities in the area of electrochemical energy storage for powering smart and miniaturized electronic devices. Here we design an asymmetric micro-supercapacitor (A-MSC) combining sputtered vanadium nitride film (VN) and…

A Novel Multi-Level Pyramid Co-Variance Operators for Estimation of Personality Traits and Job Screening Scores

Hichem Telli, Salim Sbaa, Salah Eddine Bekhouche, Fadi Dornaika, Abdelmalik Taleb-Ahmed, Miguel Bordallo López

Recently, automatic personality analysis is becoming an interesting topic for computer vision. Many attempts have been proposed to solve this problem using time-based sequence information. In this paper, we present a new framework for estimating the Big-Five personality traits and job candidate…

Alpha-stable model for interference in IoT networks

Laurent Clavier, Troels Pedersen, Ignacio Rodriguez Larrad, Malcolm Egan

The increase in connected device, linked with the evolution of IoT and cellular networks with 5G and towards 6G makes crucial the limitation of the interference impact. Devices in networks (like LoRa, SigFox and even WiFi) or in different networks are not necessarily coordinated to optimize their…
