Near-self-imaging cavity for three-mode optoacoustic parametric amplifiers using silicon microresonators

J. Liu, F. A. Torres, Y. Ma, C. Zhao, L. Ju, D. G. Blair, S. Chao, I. Roch-Jeune, R. Flaminio, C. Michel, K.Y. Liu

Three-mode optoacoustic parametric amplifiers (OAPAs), in which a pair of photon modes are strongly coupled to an acoustic mode, provide a general platform for investigating self-cooling, parametric instability and very sensitive transducers. Their realization requires an optical cavity with…

Dielectric relaxation analysis of Pb(Zr_0.54,Ti_0.46)O₃ thin films: electric field dependence

Freddy Ponchel, N. Sama, Denis Remiens, T. Lasri

350 nm-thick Perovskite PbZr0.54Ti0.46O3 (PZT) thin films were deposited on Al2O3 substrates by sputtering with and without an additional 10-nm-thick TiOx buffer layer. X-ray diffraction patterns showed that in presence of TiOx buffer layer, PZT film was highly oriented along the (111) direction…

Cross-talk artefacts in Kelvin probe force microscopy imaging : a comprehensive study

Sophie Barbet, Michka Popoff, Heinrich Diesinger, D. Deresmes, Didier Theron, Thierry Melin

We provide in this article a comprehensive study of the role of ac cross-talk effects in Kelvin Probe Force Microscopy (KPFM), and their consequences onto KPFM imaging. The dependence of KPFM signals upon internal parameters such as the cantilever excitation frequency and the projection angle of…

[Review] Generation of transversal envelope soliton in polymeric and wooden rods

M. de Billy, Anne-Christine Hladky

This paper is concerned with the probing of the transversal envelope solitons propagation in circular waveguides when a set of requirements (non-linearity and dispersion) are fulfilled in the waveguide and balanced. The basic idea is to analyze the shape of an acoustic pulse after it has traveled…

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)…

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…

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…
