(Color online) Snapshots of supported liquid clusters at and the corresponding caloric curves. The left panel shows flattening of clusters with Fe-substrate interaction strength increasing from to . The caloric curve for the free cluster is shown for comparison.
(Color online) Lindemann indices for the free (a) and supported (b) clusters just below their melting points. The free cluster is at (melting point ) and the supported cluster, , is at (melting point ). The insets are snapshots of the clusters where the high mobility atoms (Lindemann index ) are highlighted. One-quarter of the cluster is removed to show the inner atoms.
Illustration of the effective diameter, , obtained from the cluster curvature for weak (a) and strong (b) substrate adhesions. The diameter, , and height, , that would be measured by electron microscopy is also shown.
(Color online) The melting point dependence on the inverse of free cluster diameter, , and supported cluster effective diameter, , for clusters containing atoms and cluster-substrate interaction strengths from to . The dashed and solid lines are linear fits to the free and supported cluster data, respectively.
