    "abstract": "The melting transition of the five different lattices of a bilayer crystal is\nstudied using the Monte-Carlo technique. We found the surprising result that\nthe square lattice has a substantial larger melting temperature as compared to\nthe other lattice structures, which is a consequence of the specific topology\nof the temperature induced defects. A new melting criterion is formulated which\nwe show to be universal for bilayers as well as for single layer crystals.",
