Transport properties of nonhomogeneous segregated composites
B. Nigro, G. Ambrosetti, C. Grimaldi +2
In conductor-insulator composites in which the conducting particles are dispersed in an insulating continuous matrix the electrical connectedness is established by interparticle qu…
Percolation-to-hopping crossover in conductor-insulator composites
G. Ambrosetti, I. Balberg, C. Grimaldi
Here, we show that the conductivity of conductor-insulator composites in which electrons can tunnel from each conducting particle to all others may display both percolation and tun…
Solution of the tunneling-percolation problem in the nanocomposite regime
G. Ambrosetti, C. Grimaldi, I. Balberg +3
We noted that the tunneling-percolation framework is quite well understood at the extreme cases of percolation-like and hopping-like behaviors but that the intermediate regime has…
Filler Dependencies of Electrical Conductivity in Nanotube and Nanofiber Composites
G. Ambrosetti, C. Grimaldi, T. Maeder +2
We report on a model of polymer nanocomposites with fibrous fillers which explicitly considers the microscopic filler features and replicates the composites as random distributions…
Percolative properties of hard oblate ellipsoids of revolution with a soft shell
Gianluca Ambrosetti, Niklaus Johner, Claudio Grimaldi +2
We present an in-depth analysis of the geometrical percolation behavior in the continuum of random assemblies of hard oblate ellipsoids of revolution. Simulations where carried out…
