Dissociation of charge transfer states and carriers separation in bilayer organic solar cells - A time-resolved electroabsorption spectroscopy study

Jacques-Edouard Moser, Roland Hany, Jelissa Risse

Ultrafast optical probing of the electric field by means of Stark effect in planar heterojunction cyanine dye / fullerene organic solar cells enables to directly monitor the dynamics of free electron formation during the dissociation of interfacial charge ...

Dry sliding contact between rough surfaces at the atomistic scale

Jean-François Molinari, Guillaume Anciaux, Peter Spijker

Although, a lot is known about the factors contributing to friction, a complete physical understanding of the origins of friction is still lacking. At the macroscale several laws have long since described the relation between load (Amontons, Coulomb), appa ...

Atoms and quantum dots with a large number of electrons: The ground-state energy

Hervé Kunz, Rico Rueedi

We compute the ground-state energy of atoms and quantum dots with a large number N of electrons. Both systems are described by a nonrelativistic Hamiltonian of electrons in a d-dimensional space. The electrons interact via the Coulomb potential. In the cas ...

Understanding, 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 ...

Exact results for thermodynamics of the hydrogen plasma: Low-temperature expansions beyond Saha theory

We study hydrogen in the Saha regime, within the physical picture in terms of a quantum proton-electron plasma. Long ago, Saha showed that, at sufficiently low densities and low temperatures, the system behaves almost as an ideal mixture made with hydrogen ...

Near-field spectroscopy and theoretical modeling of disordered semiconductor quantum wires

Andrea Feltrin

In this thesis work, we report scanning near-field optical photoluminescence spectroscopy measurements with at best 200 nm spatial resolution performed on disordered semiconductor V-groove AlGaAs/GaAs quantum wires. In order to interpret the results of the ...

29Si NMR chemical shifts of silane derivatives

Geometries and 29Si NMR chem. shifts are calcd. for silanes SinH2n+2, n=1,...,5, methylsilanes SiHnMe4-n, methoxysilanes SiHn(OMe)4-n, and methylmethoxysilanes SiMen(OMe)4-n, n=0,...,4. Geometries and 29Si NMR chem. shifts are in satisfying agreement with ...

Multi-finger manipulation of virtual objects

Daniel Thalmann, Ronan Boulic

The manipulation of a virtual object by means of a digital glove is a tedious task for repetitive position and orientation adjustments. We try to overcome the lack of force feedback of general purpose digital gloves. We propose a solution based only on the ...

Quantum Many-Body States of Excitons in a Small Quantum-Dot

Marc-André Dupertuis

Quantum many-body states of up to four excitons are studied in small parallelepipedal quantum dots with only two nondegenerate electronic levels in the conduction and in the valence bands. Only one type of hole is considered. We find the set of good quantu ...
