Complex transport in strongly disordered materials
The Lorentz model constitutes a reference model for transport in disordered materials. Here a tracer meanders through an array of frozen obstacles which in the simplest variant are assumed to be distributed independently. As the density of scatterers increases, the regions of excluded volume start to overlap until eventually long-range transport ceases to exist entirely. This localization trans...
متن کاملInterlayer transport in disordered semiconductor electron bilayers.
We study the effects of disorder on the interlayer transport properties of disordered semiconductor bilayers by performing self-consistent quantum transport calculations. We find that the addition of material disorder to the system affects the interlayer interactions leading to significant deviations in the interlayer transfer characteristics. In particular, we find that disorder decreases and...
متن کاملElectron transport in disordered graphene nanoribbons.
We report an electron transport study of lithographically fabricated graphene nanoribbons (GNRs) of various widths and lengths. At the charge neutrality point, a length-independent transport gap forms whose size is inversely proportional to the GNR width. In this gap, electrons are localized, and charge transport exhibits a transition between thermally activated behavior at higher temperatures ...
متن کاملAnderson localization in strongly coupled disordered electron-phonon systems
Based on the statistical dynamical mean field theory, we investigate, in a generic model for a strongly coupled disordered electron-phonon system, the competition between polaron formation and Anderson localization. The statistical dynamical mean field approximation maps the lattice problem to an ensemble of self-consistently embedded impurity problems. It is a probabilistic approach, focusing ...
متن کاملElectron Transport Through Molecular Structures
Electron transport through molecular structures is investigated with three different concepts. Polythiophenyl substituted benzenes were studied as reducible substructures in molecular architectures. By linking two reducible substructures with different bridging motives the potential of the bridging structure as electronic connector was investigated. Diacetylene turned out to be the most promisi...
