Quantum effects in the resistivity of percolation metal networks

Artikel i vetenskaplig tidskrift, 1995

We have studied the quantum corrections to the resistance of two-dimensional (2D) percolation networks of quasi-one-dimensional (1D) wires in which the ratio between the percolation correlation length and the quantum lengths L,LT could be controllably changed over a wide range. We have shown that the percolation networks behave like homogeneous 2D conductors with respect to the quantum corrections if L, LT. Close to the percolation threshold (L, LT) a crossover to 1D quantum corrections is observed
