Extract

We have investigated the influence of C1− and Fe3+ ions on the morphology of pits grown in aluminium thin films, under open circuit conditions. We observed various morphologies ranging from percolation-cluster-like patterns to dense holes with smooth perimeters. The experimental behavior has been appropriately simulated by a spreading percolation model with feed-back. This model reproduced all the morphologies observed and sustains the mechanisms proposed.
