Effect of geometry on electrical percolation in nanocomposites with impenetrable ellipsoidal inclusion

This paper is devoted to study isotropic and anisotropic percolation threshold of ellipsoidal inclusions utilizing 3D Monte Carlo simulation. Electrically percolated inclusions yield in electrical conductivity that is a special feature of nanocomposites. Electrical percolation is influenced by so many factors and conditions such as electron tunneling distance, geometry, anisotropy and mixing of inclusions. In the present work the percolation threshold analyzed considering the effect of geometry, by options of different tunneling distances and aspect ratios. In the case of anisotropic several orientation ranges studied to assess its influence on percolation threshold, and to achieve the range during which percolation threshold become minimum. Percolation threshold decreases as tunneling distance and aspect ratio increases. In isotropic cases the percolation threshold is less than anisotropic ones
