An electrical percolation model for tin dioxide polycrystalline thin films

Abstract : The physical properties of tin dioxide and its electrical performance largely depend on its morphological properties. As mentioned by several authors, the size of crystallites relative to the Debye length appears to be a determining factor for the sensitivity to gas. In a previous paper concerning thin films elaborated by reactive evaporation, it has been established that the electrical conductivity value depends on the relative density of the film.
