Conference paper (other academic/artistic)abstract
- At low temperatures, the quantum corrections to the resistance due to weak localization and electron-electron interaction are affected by the shape and topology of samples. We observed these effects in the resistance of 2D percolation networks made from 1D wires and in a series of long 1D wires with regularly spaced side branches. Branches outside the classical current path strongly reduce the quantum corrections to the resistance and these reductions become a measure of the quantum lengths

- We have studied the quantum corrections to the resistance of one-dimensional gold wires with periodically spaced dangling side branches. Both the weak localization and interaction corrections to the resistance of such samples are strongly reduced when the distance between branches becomes smaller than the quantum length scales. The dependence of the quantum corrections on the distance between the branches then becomes a measurement of the quantum lengths

Journal article (peer-reviewed)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 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
