摘要：

The melting transition of the five different lattices of a bilayer crystal is studied using the Monte Carlo technique. The square lattice has a substantially larger melting temperature than that of the other lattice structures, which is a consequence of the specific topology of temperature-induced defects. A new melting criterion, universal for bilayers as well as for single layer crystals, is formulated.
