Enhanced tunneling conductivity induced by gelation of attractive colloids

Biagio Nigro, Claudio Grimaldi, Peter Ryser +3

We show that the formation of a gel by conducting colloidal particles leads to a dramatic enhancement in bulk conductivity, due to inter-particle electron tunneling, combining pred…

Quasiuniversal connectedness percolation of polydisperse rod systems

Biagio Nigro, Claudio Grimaldi, Peter Ryser +2

The connectedness percolation threshold (eta_c) and critical coordination number (Z_c) of systems of penetrable spherocylinders characterized by a length polydispersity are studied…

Tunneling and percolation transport regimes in segregated composites

B. Nigro, C. Grimaldi, P. Ryser

We consider the problem of electron transport in segregated conductor-insulator composites in which the conducting particles are connected to all others via tunneling conductances,…

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…
