Photoassisted tunneling from free-standing GaAs thin films into metallic surfaces

D. Vu, S. Arscott, Emilien Peytavit, R. Ramdani, E. Gil, Y. André, S. Bansropun, B. Gerard, A. Rowe, D. Paget

The tunnel photocurrent between a gold surface and a free-standing semiconducting thin film excited from the rear by above bandgap light has been measured as a function of applied bias, tunnel distance and excitation light power. The results are compared with the predictions of a model which…

Two-dimensional phononic crystals: Examples and applications

Yan Pennec, Jerome O. Vasseur, Bahram Djafari-Rouhani, L. Dobrzynski, Pierre Deymier

Phononic crystals are composite materials made of periodic distributions of inclusions embedded in a matrix. Due to their periodic structure, these materials may exhibit under certain conditions, absolute acoustic band gaps i.e. forbidden bands that are independent of the direction of propagation…

Droplet motion and deformation induced by acoustic streaming and radiation pressure

Philippe Brunet, Michael Baudoin, Olivier Bou Matar, Farzam Zoueshtiagh

Rayleigh Acoustic waves generated at the surface of a solid substrate can induce deformation, motion and even atomization of partially wetting droplets. The characteristic time scales associated with the droplets response strongly differ from the acoustic period, suggesting the existence of…

Tetrathiafulvalene End-Functionalized Poly( N -isopropylacrylamide): A New Class of Amphiphilic Polymer for the Creation of Multistimuli Responsive Micelles

Julien Bigot, Bernadette Charleux, Graeme Cooke, François Delattre, David Fournier, Joël Lyskawa, Léna Sambe, François Stoffelbach, Patrice Woisel

In this article, we report the formation of micelles from a tetrathiafulvalene (TTF) end-functionalized poly(N-isopropylacrylamide) (poly(NIPAM)) derivative (1). We have determined the critical aggregation concentration (CAC) and average diameter of the micelles using fluorescence spectroscopy and…

Mapping charge transfers between quantum levels using noncontact atomic force microscopy

Lukasz Borowik, Koku Kusiaku, D. Deresmes, Didier Theron, Heinrich Diesinger, Thierry Melin, Thuat Nguyen-Tran, Pere Roca I Cabarrocas

We demonstrate the possibility to map nanoscale charge transfers between quantum electronic levels at room temperature, using noncontact atomic force microscopy and Kelvin force microscopy in a regime of weak electromechanical coupling. A two-level system is studied, consisting of degenerately…

Optimal power distribution over pilot tones for multi-carrier communications over power lines

David Buèche, Patrick Corlay, François-Xavier Coudoux, Marc G. Gazalet, Marc Slachciak

In this paper, we propose a method for finding the optimal distribution of pilot power, which will optimize the performance of multi-carrier transmissions over power lines, using comb-type pilots. To find this optimal distribution, we took noise characteristics and channel estimation techniques…

Replication of the Trouton-Noble Experiment

Robert Gabillard, Christian Semet, Patrick Cornille, Christian Bizouard

The basic aim of the 1903 Trouton-Noble experiment was to detect an absolute motion of the Earth through the ether. The experiment presented in this paper is a replication of the Trouton-Noble experiment done with present technology, free from previous imperfections. Contrary to previous results, a…

Electronic properties of the high electron mobility Al0.56In0.44Sb/Ga0.5In0.5Sb heterostructure

L. Desplanque, D. Vignaud, S. Godey, E. Cadio, S.R. Plissard, X. Wallart, Peng Liu, Hermann Sellier

Electronic properties of the Al0.56In0.44Sb/Ga0.5In0.5Sb heterostructure grown by molecular beam epitaxy are investigated. We measure by means of x-ray photoemission spectroscopy, photoluminescence, and Hall effect measurements the key parameters involved in the achievement of a high speed and very…
