Surface Melting (faceting?)

Surface Melting (faceting?). Sergio Calatroni. Surface Melting. (110) -> 1270 K (1000 C) (100) -> 1290 K (1020 C) (111) -> 1310 K (1040 C). Bulk fusion -> Lindemann criterion: rms thermal vibration amplitude of the solid reaches some 14% of the nearest-neighbour distance.
