【摘要】 采用表面界面生长方程动力学标度奇异性的动力学重整化群理论,分析了线性和非线性分子束外延生长方程(molecular-beam epitaxy(MBE))的动力学标度奇异性.结果表明,生长方程的动力学标度性质与基底的维数d有关,只有d的取值满足一定条件时,生长方程才会出现奇异动力学标度行为,这和使用直接标度分析方法得到的结果一致.更多还原

【Abstract】 A dynamic renormalization-group method is applied to analysis the anomalously dynamic scaling property of kinetic roughening growth equation of the linear and non-linear molecular-beam epitaxy growth equations.Our analyses show that the dynamic scaling property of a growth equation is relative to the dimension of the system,and can be observed only for the special value of the substrate dimension.These results obtained here are consistent with previous calculations by use of scaling analysis.更多还原
