Percolation and Area1 Electrical Conductance in an Ultra Thin Bismuth Film

Percolation models have been briefly discussed. The two dimensional continuum percolation model was applied to the analysis of the area1 electrical conductance as well as the bulky electrical conductivity of an ultra-thin bismuth film. The results of the normalized area1 electrical conductance against the area fraction covered by islands on the substrate have been found to behave m&h smoother and reasonable in the slope and curvature than those based on the corresponding bulky conductivity, indicating again that the system be a two-dimensional film.
