• The commensurate-incommensurate phase transition in crystals in driven by the nuclei called stripples. The stripple has a structure defined by the symmetries of crystal phases. It is nucleated as a result of thermal fluctuations. Since a macroscopic number of stripples is needed to complete the phase transition a collective nucleation can take place. There are two ideal mechaniscms of collective stripple nucleations : cascade and serial ones. The stripple appearences are illustrated by the results of mocelular-dynamics simulation on the model systems.Commensurate-incommensurate phase transitionnucleation of stripplesmolecular dynamics
