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…

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…

Optimal Percolation of Disordered Segregated Composites

N. Johner, C. Grimaldi, T. Maeder +1

We evaluate the percolation threshold values for a realistic model of continuum segregated systems, where random spherical inclusions forbid the percolating objects, modellized by…

Tunneling-percolation origin of nonuniversality: theory and experiments

S. Vionnet-Menot, C. Grimaldi, T. Maeder +2

A vast class of disordered conducting-insulating compounds close to the percolation threshold is characterized by nonuniversal values of transport critical exponent t, in disagreem…

Strain modulation of transport criticality in heterogeneous solids

Sonia Vionnet, Claudio Grimaldi, Thomas Maeder +2

A vast class of disordered conducting-insulating compounds close to the percolation threshold is characterized by nonuniversal values of transport critical exponents. The lack of u…
