Low work function thin film growth for high efficiency thermionic energy converter : coupled Kelvin probe and photoemission study of potassium oxide

François Morini, Emmanuel Dubois, J.F. Robillard, Stéphane Monfray, Thomas Skotnicki

Recent researches in thermal energy harvesting have revealed the remarkable efficiency of thermionic energy converters comprising very low work function electrodes. From room temperature and above, this kind of converter could supply low power devices such as autonomous sensor networks. In this…

Hypersonic band gap in an AlN-TiN bilayer phononic crystal slab

S. Hemon, Abdellatif Akjouj, A. Soltani, Yan Pennec, Y. El Hassouani, Abdelkrim Talbi, V. Mortet, Bahram Djafari-Rouhani

We show both theoretically and experimentally the existence of a complete band gap in a phononic crystal (PnC) constituted by periodical air holes drilled in a solid bi-layer slab. The composite slab is formed with an aluminum nitride (AlN) layer deposited on a titanium nitride (TiN) thin metallic…

Optimization of the optical properties of nanostructured silicon surfaces for solar cell applications

Di Zhou, Yan Pennec, Bahram Djafari-Rouhani, Odile Cristini-Robbe, Tao Xu, Yannick Lambert, Yves Deblock, Marc Faucher, Didier Stiévenard

Surface nanostructuration is an important challenge for the optimization of light trapping in solar cell. We present simulations on both the optical properties and the efficiency of micro pillars--MPs--or nanocones--NCs--silicon based solar cells together with measurements on their associated…

Electrical and Chemical studies on Al2O3 passivation activation process

M. Pawlik, J-P. Vilcot, M. Halbwax, D. Aureau, A. Etcheberry, A. Slaoui, T. Schutz-Kuchly, R. Cabal

Al2O3 deposited using Atomic layer Deposition (ALD) technique is known as an excellent material for p-type silicon surface passivation. However a post-deposition annealing step is needed to make the passivation effective. Thanks to coupled electrical measurements (capacitance and photoconductance)…

Image and many-body effects in ultra-thin gate insulator MOSFET with In0.53Ga0.47As channel material and their influence on gate leakage current

Gabriel Mugny, D. Rideau, F. Triozon, Yann-Michel Niquet, F.G. Pereira, A. Soussou, I. Duchemin, D. Garetto, C. Tavernier, H. Jaouen, Christophe Delerue

We study the influence of many-body and image force corrections on charge distribution, threshold voltage and tunnel current in fully-depleted silicon-on-insulator (FDSOI) ultra-thin gate insulator MOSFETs. We show that image correction slightly increases threshold voltage in Si MOSFETs and that…

Characterization of multi-layered nanopore structure

Xiaokun Ding, Nicolas Tiercelin, Philippe Pernod, Vladimir Preobrazhensly, Yujun Song, Alexey Klimov

Hybridization of nanostructures opens new avenues for the synthesis of nano-architectures with multi-function and novel physicochemical properties. In this paper, we developed nanosphere template assisted physical vapor deposition to fabricate ordered multi-layered nanostructures utilizing Ag/…

Multiple-Antenna Based Blind Spectrum Sensing in the Presence of Impulsive Noise

Kais Hassan, Roland Gautier, Iyad Dayoub, Marion Berbineau, Emanuel Radoi

Cognitive radio was proposed as a solution to the spectrum scarcity problem. One of the basic functions of any cognitive radio is the spectrum sensing. Most of the existing works on spectrum sensing consider the Gaussian noise assumption. In practice, this assumption is not always valid since…

Detection and localization of a defect in a reverberant plate using acoustic field correlation

Lynda Chehami, Emmanuel Moulin, Julien de Rosny, Claire Prada, Olivier Bou Matar, Farouk Benmeddour, Jamal Assaad

Green's function can be retrieved from cross-correlation of a diffuse field generated by noise sources. Today, this important result is the fundamental of several passive imaging techniques. The aim of this paper is to establish the suitability of these methods to detect and locate a defect in…

Broadband attenuation of Lamb waves through a periodic array of thin rectangular junctions

Rayisa P. Moiseyenko, Yan Pennec, Rémi Marchal, Bernard Bonello, Bahram Djafari-Rouhani

We study theoretically subwavelength physical phenomena, such as resonant transmission and broadband sound shielding for Lamb waves propagating in an acoustic metamaterial made of a thin plate drilled with one or two row(s) of rectangular holes. The resonances and antiresonances of periodically…
