摘要
The √3×√3R30° structure commensurate with the substrate was studied experimentally and theoretically. The equation of state using the method of molecular dynamics was successfully applied to Van der Waals systems. The pair potential of interaction between krypton atoms was assigned in the form of Lennard-Jones potential. The interaction with the substrate at zero temperature is insufficient for the atoms to take up the minima of the substrate potential. The formation of symmetric phase was identified by special features in the behavior of structure factor of scattering. The initial velocities and their directions were assigned at random and are redefined for the purpose of eliminating the motion of the system as a whole, which corresponds to the transition to the system of center of mass. The equation is well approximated by the Van der Waals dependence, which enables one to express the critical temperature in terms of Van der Waals constants.
