Octahedral ordering starting from an amorphous deposit

Amorphous to crystalline transition in an AB2 type system on sapphire. MD description. Two competing nucei corresponding to calcium chloride and cadmium iodide type structures emerge. This co-crystallisation stabilizes the cacl2 structure long enough for experimental observation. 
The video shows octahedral ordering in a 3 angstrom wide layer of the Mgf2 deposit on annealing the substrate.
