| Abstract: | The growth of ABAC structured film by means of pulsed laser deposition was simulated by the Monte Carlo procedure.In the model,we introduced the three-hollow site with a layer dislocation in order to realize the ABAC growth mode.The quality of the film is controlled by three parameters,namely,the temperature of the substrate,the kinetic energy of the atoms and the coverage of per pulse.The simulated results show that the quality of the films is strongly dependent on the three parameters.We analyzed the mism... |
