Cu3Au薄膜中的［001］方向反相畴界

The order-disorder transition of the Cu₃Au film system is simulated by the Monte Carlo method. The computational results show that the antiphase boundaries in the film have different properties with antiphase boundaries in the bulk. The kind of ［001］ antiphase boundaries in the film is determined by the parity of the layer number of the film. For even-layer number film, only the non- conservative antiphase boundaries appear in the film; for the odd-layer number film, only conservative antiphase boundaries may appear. Like the situation in the bulk materials, the simulation indicates that only the non-conservative antiphase boundary wet.
