Abstract
In situ transport measurements during the growth of a thin layer of th ermally evaporated tellurium onto an oriented polymer film are present ed. The system, which resembles the characteristics of a two-dimension al anisotropic network, is analyzed in terms of the current percolatio n theory. Parameters such as the percolation threshold and the critica l exponents are calculated for the perpendicular and the parallel orie ntation. Within the limits of the experiments the values of t(parallel to) and t(perpendicular to) are estimated to be 1.15 and 1.46, respec tively.
