Mechanism of the Transition from Fractal to Dendritic Growth of Surface Aggregates

Klaus Kern, Harald Brune

THE similarity of many patterns formed in non-equilibrium growth processes in physics, chemistry and biology is conspicuous, and many attempts have been made to discover common mechanisms underlying their formation(1). A central question is what causes som ...
