Percolation and Conductivity of Network of Hard Rods under Mechanical Load — •Arshia Atashpendar and Tanja Schilling — Physikalisches Institut, Albert-Ludwigs-Universität, 79104 Freiburg, Germany

Electrically conductive, soft nano-composites are of technological interest e.g. as transparent electrodes and as sensors. The dielectric behaviour of these systems under varying mechanical conditions still remains poorly investigated. Thus, in order to better understand the conductivity properties of dispersed conductive nano-particles in an insulating matrix, we use Monte Carlo simulations to study how the structure of the percolating network, the conductivity and the diffusive properties of a system of isotropic hard rods are affected by mechanical load. The conductance between pairs of rods is considered under the assumption that single electron tunneling is the sole dominant process for electrical connectedness.
