Modeling and simulation of InAs/GaAs quantum dots for solar cell applications

A. Benahmed, Abdelkader Aissat, Abdelmalek Benkouider, Jean-Pierre Vilcot

This paper proposes a method of modeling and simulation of InAs/GaAs-based quantum dots (QDs) for solar cell. The main objective is to find the growth parameters in order to produce an optimal double heterostructure using two semiconductor materials InAs and GaAs. We are interested in particular on...

Enhanced ultraviolet luminescence of ZnO nanorods treated by high-pressure water vapor annealing (HWA)

Amer Al-Nafiey, Brigitte Sieber, B. Gelloz, Ahmed Addad, M. Moreau, Julien Barjon, Maria Girleanu, Ovidiu Ersen, Rabah Boukherroub

Zinc oxide nanorods (ZnO NRs), synthesized by a low temperature chemical method, were postannealed at 260°C in air and under high pressure water vapor (HWA) at 1.3-3.9 MPa. We found that the UV luminescence intensity increased by a factor of 2-3 after HWA annealing compared to that observed after...

Preparation and characterization of Ni-doped ZnO–SnO₂ nanocomposites: Application in photocatalysis

Monaam Ben Ali, Fatiha Barka-Bouaifel, Brigitte Sieber, Habib Elhouichet, Ahmed Addad, Luc Boussekey, Mokhtar Férid, Rabah Boukherroub

The paper reports on the synthesis of nickel-doped ZnO-SnO₂ nanocomposites with a molar ratio Zn:Sn of 2:1 using the hydrothermal method followed by calcination at 700 °C. The resulting nanocomposites were characterized using X-ray diffraction (XRD) patterns, transmission...

METASTABILITY OF FINITE STATE MARKOV CHAINS: A RECURSIVE PROCEDURE TO IDENTIFY SLOW VARIABLES FOR MODEL REDUCTION

Claudio Landim, T. Xu

Consider a sequence (η N (t) : t ≥ 0) of continuous-time, irreducible Markov chains evolving on a fixed finite set E. Denote by R N (η, ξ) the jump rates of the Markov chain η N t , and assume that for any pair of bonds (η, ξ),

Improved performance of flexible CMOS technology using ultimate thinning and transfer bonding

Emmanuel Dubois, Justine Philippe, Matthieu Berthomé, J.F. Robillard, Christophe Gaquière, Francois Danneville, Daniel Gloria, Christine Raynaud

Based on a simple process referred to as ultimate thinning-and-transfer-bonding (UTTB), this paper shows that the high-frequency performance of advanced CMOS technologies can be combined with mechanical flexibility and transparency. The invariance upon thinning, transfer and flexure of both DC and...

Toward Energy Profiling of Connected Embedded Systems

Nadir Cherifi, Gilles Grimaud, Alexandre Boé, Thomas Vantroys

A huge number of connected objects are expected to be deployed over the coming years in various areas of everyday life. Many of these objects are energy-constrained and depend on a battery. Thus, energy is a critical resource that limits a large scale deployment, and greatly complicates the...

DS-UWB and TH-UWB Energy Consumption Comparison

Adil Elabboubi, Fouzia Elbahhar, Marc Heddebaut, Yassin El Hillali

The energy consumption of the wireless communication systems is starting to be unaffordable. One way to improve the power consumption is the optimization of the communication techniques used by the communication networks and devices. In order to develop an energy efficient UWB multi-user...

AlN/IDT/AlN/Sapphire SAW Heterostructure for High-Temperature Applications

Ouarda Legrani, Thierry Aubert, Omar Elmazria, Ausrine Bartasyte, Pascal Nicolay, Abdelkrim Talbi, Pascal Boulet, Jaafar Ghanbaja, Denis Mangin

Recent studies have evidenced that Pt/AlN/Sapphire SAW devices are promising for high-temperature high-frequency applications. However, they cannot be used above 700°C in air atmosphere as the Pt interdigital transducers (IDTs) agglomerate and the AlN layer oxidizes in such conditions. In this...
