Qausi-equilbiurm heating of {110} rod with a fixed core (3 layers)


The core of the {110} rod has been fixed so that only the three outmost layers can move. It was heated up step by step with the temperature interval of 100K. At each temperature 10^6 MD steps have been performed.

Surface and Cross-section pictures

They are the last configurations at each temperature. Brown spheres represent fixed core atoms. For surface, golden atoms represent {111} facets, green atoms represent {100} atoms, and gray atoms are others. For interior, golden atoms have a local fcc structure, green atoms have a local hcp structure, and gray atoms have neither.
