Recently Deutscher and Lareahl discovered a new mode of phase separation in thin films of Al/Ge alloys. They observe the growth of circular “colonies” whose densely packed appearance has been called “dense branching morphology”? The colonies consist of a highly branched starlike “island” of polycrystalline Ge inside a “lake” of monocrystalline Al which is only slightly larger than the Ge island. Thus the Al forms a thin but essentially uninterrupted rim around the Ge peninsulas. The whole colony is embedded in the amorphous phase having an overall composition of 40% Al and 60% Ge. As these colonies grow into the metastable amorphous surrounding they preserve their more or less circular shape.
