摘要：

We investigate the relation between the thermodynamic stability of periodic and quasiperiodic crystals and the characteristics of the interaction potential within a simple van der Waals approximation to the free energy of a one-component two-dimensional system We find that thermodynamically stable quasiperiodic crystals can be found only when the interaction potential has at least two negative minima separated by a positive maximum.
