Query: Hole-initiated melting process of thin films   It is generally believed that melting of a thin film starts from a small
defect, e.g., a hole on the film that acts as the nucleation site. We show in
this study that when the contribution of the capillary surface (liquid/air
interface) is taken into consideration, the melting process is non-trivial: 1)
There may be multiple melting pathways for one system, and hence different "de
facto" melting points. 2) Melting of a thin film may start from the long,
straight edge rather than the small holes if the edge facet wets better than
the substrate. This is verified by experimental data from melting alkane layers
between silica and air. Our findings provides a general approach for solving
the non-trivial melting scenarios in systems with capillary surfaces.
