Abstract

Mechanisms for the formation of two-dimensional fractal shapes in metal-on-metal growth have been investigated theoretically. It is shown that an extended fractal growth regime, characterized by significant local edge diffusion, exists on triangular but not on square lattices. Simulations to fit observed data allow estimates of the activation barrier for edge diffusion.
