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...

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...

Terahertz response of InGaAs field effect transistors in quantizing magnetic fields

Oleg Klimenko, Yu. Mityagin, Hadley Videlier, Frederic Teppe, N. Dyakonova, Christophe Consejo, S. Bollaert, V. Murzin, Wojciech Knap

Terahertz (THz) detection by plasma wave mechanism in InGaAs field effect transistors is studied in high/quantizing magnetic fields regime. The correlation between the photovoltaic response and magnetoresistance is revealed. It allows explaining the dominant physical mechanism responsible for...
