Title: Quantum Effects in the Resistivity of Percolation Metal Networks
Abstract: 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 $\ensuremath{\xi}$ and the quantum lengths ${L}_{\ensuremath{\phi}}$, ${L}_{T}$ 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 $\ensuremath{\xi}<{L}_{\ensuremath{\phi}}, {L}_{T}$. Close to the percolation threshold ($\ensuremath{\xi}\ensuremath{\gg}{L}_{\ensuremath{\phi}}, {L}_{T}$) a crossover to 1D quantum corrections is observed.
