Stationary Velocity and Charge Distributions of Grains in Dusty Plasmas

A. G. Zagorodny, P. P. J. M. Schram, S. A. Trigger

Within the kinetic approach velocity and charge distributions of grains in stationary dusty plasmas are calculated and the relations between the effective temperatures of such dist…

Ab-initio calculation of the electronic and optical excitations in polythiophene: effects of intra- and interchain screening

J. -W. van der Horst, P. A. Bobbert, M. A. J. Michels +2

We present an calculation of the electronic and optical excitations of an isolated polythiophene chain as well as of bulk polythiophene. We use the GW approximation for the electro…

Dopant-induced crossover from 1D to 3D charge transport in conjugated polymers

J. A. Reedijk, H. C. F. Martens, H. B. Brom +1

The interplay between inter- and intra-chain charge transport in bulk polythiophene in the hopping regime has been clarified by studying the conductivity as a function of frequency…

Sn delta-doping in GaAs

V. A. Kulbachinskii, V. G. Kytin, R. A. Lunin +7

We have prepared a number of GaAs structures delta-doped by Sn using the well-known molecular beam epitaxy growth technique. The samples obtained for a wide range of Sn doping dens…

Inhomogeneity of dusty crystals and plasma diagnostics

L. I. Podloubny, P. P. J. M. Schram, S. A. Trigger

Real dusty crystals are inhomogeneous due to the presence of external forces. We suggest approximations for calculations of different types of inhomogeneous DC (chain and DC with a…

Transport spin polarization of Ni_xFe_{1-x}: electronic kinematics and band structure

B. Nadgorny, R. J. Soulen, M. S. Osofsky +7

We present measurements of the transport spin polarization of Ni_xFe_{1-x} (0<x<1) using the recently-developed Point Contact Andreev Reflection technique, and compare them with ou…

Preparation and measurement: two independent sources of uncertainty in quantum mechanics

Willem M. de Muynck

In the Copenhagen interpretation the Heisenberg uncertainty relation is interpreted as the mathematical expression of the concept of complementarity, quantifying the mutual disturb…
