Experimental observation of an enhanced anisotropic magnetoresistance in non-local configuration
We compare non-local magnetoresistance measurements in multi-terminal Ni nanostructures with corresponding local experiments. In both configurations, the measured voltages show the characteristic features of anisotropic magnetoresistance (AMR). However, th ...
American Institute of Physics2011Two-Photon Excited Fluorescence Enhancement for Ultrasensitive DNA Detection on Large-Area Gold Nanopatterns
Ultrasensitive DNA detection using enhanced two-photon excited fluorescence: DNA detection systems formed on a highly regular gold nanopattern over a large area show enhanced sensitivity from high to ultralow concentrations (similar to 10-11 M, see figure) ...
2010Degenerate crossing numbers
Let G be a graph with n vertices and ea parts per thousand yen4n edges, drawn in the plane in such a way that if two or more edges (arcs) share an interior point p, then they properly cross one another at p. It is shown that the number of crossing points, ...
Springer-Verlag2009Understanding, Controlling and Programming Cooperativity in Self-Assembled Polynuclear Complexes in Solution
Deviations from statistical binding, that is cooperativity, in self-assembled polynuclear complexes partly result from intermetallic interactions Delta E-M,E-M, whose magnitudes in solution depend on a balance between electrostatic repulsion and solvation ...
2009Room-temperature polariton lasing in semiconductor microcavities
Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Eric Feltin, Gabriel Christmann
We observe a room-temperature low-threshold transition to a coherent polariton state in bulk GaN microcavities in the strong-coupling regime. Nonresonant pulsed optical pumping produces rapid thermalization and yields a clear emission threshold of 1 mW, co ...
2007Checkerboard order in the – model on the square lattice
Frédéric Mila, Cédric Weber, Michael Sigrist
We propose that the inhomogeneous patterns seen by STM in some underdoped superconducting cuprates could be related to a bond-order-wave instability of the staggered flux state, one of the most studied “normal” state proposed to compete with the d-wave RVB ...
20073D-ITIES supported on porous reticulated vitreous carbon
Hubert Girault, Bin Su, Mohamad Hojeij, Nicolas Eugster
A thin aqueous film prepared by layer-by-layer assembly of oppositely charged polypeptides on 4-aminobenzoic acid modified porous reticulated vitreous carbon (RVC) electrodes was used with the aim of forming a 3D-ITIES. The film containing a redox mediator ...
2007Room-temperature polariton luminescence from a bulk GaN microcavity
Nicolas Grandjean, Jean-François Carlin, Marc Ilegems, Raphaël Butté, Eric Feltin, Gabriel Christmann, Mauro Mosca
We report strong exciton-photon coupling at room temperature in a hybrid high quality bulk 3 lambda/2 GaN cavity with a bottom lattice-matched AlInN/AlGaN distributed Bragg reflector through angle-resolved polarized photoluminescence (PL). Coupling of the ...
2006Well-defined surface tungstenocarbyne complexes through the reaction of [W(=CtBu)(CH(2)tBu)(3)] with silica
The molecular complex [W(&3bond; CtBu)(CH(2)tBu)(3)], 1, reacts with SiO2-(700) to give as major species 2a, [(&3bond; SiO)W(CtBu)(CH(2)tBu)(2)], while a bisgrafted surface species 3a, [(&3bond; SiO)(2)W-(&3bond; CtBu)(CH(2)tBu)], is obtained on SiO2-(200) ...
AMER CHEMICAL SOC2005Large area deposition in high vacuum with high thickness uniformity
Patrik Willi Hoffmann, Simone Amorosi, Giacomo Benvenuti
The invention relates to an effusing source for film deposition made of a reservoir comprising one hole characterized by the fact that the hole diameter is less than one order of magnitude than the mean free path of the molecules determined by the pressure ...
