COMPUTER SIMULATION OF FRACTAL BEHAVIORS IN a-Ge/Au BILAYER THIN FILMS
a-Ge/Au双层膜分形过程的计算机模拟

Based on the experimental observation, two models were proposed to described the fractal formation in a-Ge/Au films with different interfacial structures. Computer simulations were done according to the above models, the results are in agreement with experimental observations. The results also show that the local latent temperature fields play a dominant role in the fractal formation process, and the appearance of dense branching morphology is due to the local diffusion effect.
