Investigation of the charge transport through disordered organic molecular heterojunctions

Libero Zuppiroli, Eduard Tutis, Hocine Houili

We present a three-dimensional multiparticle Monte Carlo (3DMPMC) simulation of hopping transport in disordered organic molecular media. We used this approach in order to study the charge transport across an energetically disordered organic molecular heter ...

Bond-order-modulated staggered-flux phase of thetJmodel on a square lattice

Frédéric Mila, Cédric Weber

Motivated by the observation of inhomogeneous patterns in some high-Tc cuprate compounds, several variational Gutzwiller-projected wave functions with built-in charge and bond-order parameters are proposed for the extended t−J−V model on the square lattice ...

CdSe Sensitized Thin Aqueous Films: Probing the Potential Distribution Inside Multilayer Assemblies

Hubert Girault, Bin Su, Mohamad Hojeij, Nicolas Eugster

Ultrathin polypeptide multilayer films are assembled by the sequential electrostatic adsorption of monolayers of poly-L-lysine and poly-L-glutamic acid onto carboxylic acid terminated alkanethiol-modified gold surfaces. The polypeptide multilayer films are ...

Polarization effects and charge transfer in the KcsA potassium channel

Ursula Röthlisberger, Matteo Dal Peraro, Denis Bucher, Leonardo Guidoni

The electronic structure of the selectivity filter of KcsA K(+) channel is investigated by density functional theory (DFT/BLYP) and QM/MM methods. The quantum part includes the selectivity filter, which is polarized by the electrostatic field of the enviro ...

Static dielectric properties of carbon nanotubes from first principles

Nicola Marzari, Boris Kozinsky

We characterize the response of isolated single-wall (SWNT) and multiwall (MWNT) carbon nanotubes and nanotube bundles to static electric fields using first-principles calculations and density-functional theory. The longitudinal polarizability of SWNTs sca ...

Inès Lamunière

La ville est partout, la ville est nulle part. La notion de ville est une nébuleuse dans laquelle on se perd avec plus ou moins de bonheur et il n'est plus certain que l'on puisse continuer à penser la ville contemporaine en termes propres à notre culture ...

Optical injection of charge current in quantum wires: oscillations induced by excitonic effects

Benoît Marie Joseph Deveaud, Marc-André Dupertuis, Daniel Marti

We investigate the charge current that is optically injected by interference between one- and two-photon excitation in the presence of excitonic effects. We consider a realistic V-shaped quantum wire excited slightly below the band gap by two simultaneous ...

Ionic transport phenomena in nanofluidics: Experimental and theoretical study of the exclusion-enrichment effect on a chip

Philippe Renaud, Reto Bruno Schoch

In nanometer-sized apertures with charged surfaces, the extension of the electrical double layer results in the electrostatic exclusion of co-ions and enrichment in counterions, which affects the permselectivity of such structures. A modeling of this pheno ...

Advances in Precise Positioning Using the Electrostatic Glass Motor

Hannes Bleuler, Roland Moser

This paper reports the continuation of the authors' work in the field of linear and rotary submicrometric positioning using electrostatic glass motors. Electrostatic glass motors, a recent development where a glass rotor, once polarized using a static elec ...

Supported nanoclusters: Preadsorbates tuning catalytic activity

Alfredo Pasquarello, Zeljko Sljivancanin

Using a density-functional approach, we investigate the reactivity of supported metal nanoclusters. We focus on the sequential adsorption of N-2 molecules on a Fe nanocluster supported by an MgO substrate. For an increasing number of N atoms preadsorbed on ...
