Temperature dependence of the interatomic distance R for several first-nearest-neighbour Cu–Cu shells in a 6 ML Cu(111) film, together with the bulk values. 11 implies the first-and-first intralayer distance, 12 indicates the first-and-second interlayer distance, etc. (11: open squares; 22: open circles; 33: upward open triangles; 44: downward open triangles; 12: filled squares; 23: filled circles; 34: filled upward triangles; intralayer: dashed line; interlayer: solid line; bulk: crosses and dot-dashed line). |
