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...

Monte Carlo analysis of the influence of surface charges on GaN asymmetric nanochannels: bias and temperature dependence

E. Pérez-Martín, I. Íñiguez-De-La-Torre, Christophe Gaquière, T. González, J. Mateos

In this paper, the occupancy of sidewall surface states having a clear signature in the performance of AlGaN/GaN-based self-switching diodes (SSDs) is analyzed using a semi-classical Monte Carlo (MC) simulator in a wide temperature ( T) range, from 100 to 300 K. Experimental I- V curves show an...

Single-charge effects in silicon nanocrystals probed by atomic force microscopy: From charge blinking to nanocrystal charging

Thierry Melin, D. Deresmes

We investigate the electrical properties of individual silicon nanocrystals (NCs) by means of atomic/electrostatic force microscopy at atmospheric pressure, with the sensitivity of the elementary charge. Using a tip bias close to the sample surface potential for the sample topography imaging, NCs...

Two Ensemble-CNN Approaches for Colorectal Cancer Tissue Type Classification

Emanuela Paladini, Edoardo Vantaggiato, Fares Bougourzi, Cosimo Distante, Abdenour Hadid, Abdelmalik Taleb-Ahmed

In recent years, automatic tissue phenotyping has attracted increasing interest in the Digital Pathology (DP) field. For Colorectal Cancer (CRC), tissue phenotyping can diagnose the cancer and differentiate between different cancer grades. The development of Whole Slide Images (WSIs) has provided...

An effective thermal conductivity model for architected phase change material enhancer: theoretical and experimental investigations

Romain Hubert, Olivier Bou Matar, Jerome Foncin, Philippe Coquet, Dunlin Tan, Hongling Li, Edwin Hang Tong Teo, Thomas Merlet, Philippe Pernod

Phase Change Materials (pcm) have been widely used for thermal energy storage due to their high latent heat of fusion. However, PCMs suffer from their very low thermal conductivity which limits heat spreading around the heat source. Without proper thermal conductivity enhancement, melting would...

Equivalence between angular spectrum-based and multipole expansion-based formulas of the acoustic radiation force and torque

Zhixiong Gong, Michael Baudoin

Two main methods have been proposed to derive the acoustical radiation force and torque applied by an arbitrary acoustic field on a particle: The first one relies on the plane wave angular spectrum decomposition of the incident field (see Sapozhnikov and Bailey [J. Acoust. Soc. Am. 133, 661-676 (...

12 - Serial Loop Structures: Photonic Bandgaps, Confined, Cavity, and Surface Modes

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

In this chapter, we investigate the electromagnetic band structure, transmission, phase time, as well as confined and surface modes in a one-dimensional photonic structure made of loops pasted together with segments of finite length. In this serial loop structure, the loops and segments are...

A first outlook of sputtered FeWO₄ thin films for micro-supercapacitor electrodes

Gaëtan Buvat, Antonella Iadecola, Florent Blanchard, Thierry Brousse, Pascal Roussel, C. Lethien

The next generation of Internet of Things devices requires micro-supercapacitors operating at high voltage which is difficult to achieve using symmetrical design. Thus, their fabrication in an asymmetric configuration is mandatory. While MnO2 is well-established as positive electrode, the scarcity...

Enhancement of both optical and catalytic activity of copper-decorated porous silicon micro-particles

Abderrahmane Hamdi, Chohdi Amri, Rachid Ouertani, El Hadj Dogheche, Hatem Ezzaouia

To the best of our knowledge, this study is the first to investigate the effect of chemical vapour etching (CVE) combined with copper decoration on both the optical and catalytic activities of silicon micro-particles (SiμPs). After exposure to acid vapours emanating from a hot solution of hydrogen...
