Movement of surface atoms (continued)


Number of moved atoms

Atom is marked moved once its displacement from the original position is larger than 6.1 Angstrom.

The average numbers of atoms on the layers are:

T surface layer 1 layer 2 layer 3 layer 4 bulk
600K 858.9 601.9 428.1 307.7 207.4 220.0
700K 861.2 599.8 428.2 307.5 207.3 220.0
800K 862.1 600.0 427.8 307.2 207.1 219.8
900K 866.8 595.7 427.6 307.0 207.0 219.9
1000K 869.3 590.5 429.8 308.3 206.8 219.3


Average MSD of moved atoms

MSD from initial configuration to final configuration (totally 462 configurations) averaged over all moved atoms.


Average travel distance (squared) of moved atoms

Total (squared) travel distance of total 462 configurations averaged over all moved atoms.


Average MSD/travel ratio of moved atoms

Ratio of MSD vs (squared) travel distance averaged over all moved atoms.
