Colloidal nanocrystals as LEGO® bricks for building electronic band structure models

Athmane Tadjine, Christophe Delerue

Abstract The synthesis of self-assembled semiconductor nanocrystal (NC) superlattices using oriented attachment recently became a flourishing research topic. This technique already produced remarkable forms of NC superlattices, such as linear chains, mono and multilayer square lattices, and...

Optimization of pentacene double floating gate memories based on charge injection regulated by SAM functionalization

S. Li, David Guérin, Stéphane Lenfant, K. Lmimouni

Pentacene based double nano-floating gate memories (NFGM) by using gold nanoparticles (Au NPs) and reduced graphene oxide (rGO) sheets as charge trapping layers are prepared and demonstrated. Particularly, the NFGM chemically treated by 2,3,4,5,6-pentafluorobenzenethiol (PFBT) self-assembled...

An extension of the RiMAX multipath estimation algorithm for ultra-wideband channel modeling

Brecht Hanssens, Emmeric Tanghe, Davy Gaillot, M. Lienard, Claude Oestges, David Plets, Luc Martens, Wout Joseph

This work presents an extension of the high-resolution RiMAX multipath estimation algorithm, enabling the analysis of frequency-dependent propagation parameters for ultra-wideband (UWB) channel modeling. Since RiMAX is a narrowband algorithm, it does not account for the frequency-dependency of the...

Highly confined Love waves modes by defect states in a holey SiO2/quartz phononic crystal

Yuxin Liu, Abdelkrim Talbi, Philippe Pernod, Olivier Bou Matar

Highly confined Love modes are demonstrated in a phononic crystal based on a square array of etched holes in SiO2 deposited on the ST-cut quartz. An optimal choice of the geometrical parameters contributes to a wide stop-band for shear waves' modes. The introduction of a defect by removing...

10-Gb/s Indoor THz Communications Using Industrial Si Photonics Technology

Elsa Lacombe, Cybelle Belem-Gonçalves, Cyril Luxey, Frédéric Gianesello, Cédric Durand, Daniel Gloria, Guillaume Ducournau

In this letter, we report the design, fabrication, and measurement of a silicon photonics-based transmitter (Tx) offering both mass production capability and high integration level potentiality. The Tx circuit consists of an integrated photodiode generating a 200-300-GHz signal for photonic...

Optical transmission properties of an anisotropic defect cavity in one-dimensional photonic crystal

Noama Ouchani, Abdelaziz El Moussaouy, Hassan Aynaou, Youssef El Hassouani, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We investigate theoretically the possibility to control the optical transmission in the visible and infrared regions by a defective one dimensional photonic crystal formed by a combination of a finite isotropic superlattice and an anisotropic defect layer. The Green's function approach has...

GaN-on-silicon high-electron-mobility transistor technology with ultra-low leakage up to 3000 V using local substrate removal and AlN ultra-wide bandgap

Ezgi Dogmus, Malek Zegaoui, F Medjdoub

We report on extremely low off-state leakage current in AlGaN/GaN-on-silicon metal–insulator–semiconductor high-electron-mobility transistors (MISHEMTs) up to a high blocking voltage. Remarkably low off-state gate and drain leakage currents below 1 µA/mm up to 3 kV have been achieved owing to the...

Microscale ultrahigh-frequency resonant wireless powering for capacitive and resistive MEMS actuators

Yoshio Mita, Naoyuki Sakamoto, Naoto Usami, Antoine Frappé, Akio Higo, Bruno Stefanelli, Hidehisa Shiomi, Julien Bourgeois, Andreas Kaiser

This paper presents a versatile chip-level wireless driving method for microelectromechanical system (MEMS) actuators. A MEMS actuator is integrated as an electrical component of a coupled LCR resonant circuit, and it rectifies the energy sent through an ultrahigh-frequency (UHF) radio frequency (...

Wavelength characterization of an acousto-optic notch filter for unpolarized near-infrared light

Jean-Claude Kastelik, Justine Champagne, Samuel Dupont, Konstantin B. Yushkov

A cascaded system of two acousto-optical cells is proposed and experimentally demonstrated for optical notch rejection filtering in the spectral range from 1400 nm to 1600 nm. Two similar paratellurite acousto-optical devices for unpolarized light are used in a free-space gap of a fiber line....

Modeling of a Circular Ring MEMS Resonator with Voltage Excitation by Means of an Orthogonal Polynomial Method

Ismail Naciri, Abdessamad Rguiti, Lahoucine Elmaimouni, Jean-Etienne Lefebvre, Faniry Emilson Ratolojanahary, Tadeusz Gryba

The three-dimensional vibrational behavior of a piezoelectric circular ring made of a 6 mm hexagonal material is studied using Legendre polynomial method. The method is simple to implement and based on expanding the electrical potential and the mechanical displacement components in a double series...
