在考虑第一近邻和第二近邻相互作用的自洽平均场方法的框架内，研究了Kossel晶体(001)表面孤立的[110]台阶的动力学和结构。提出并定量描述了一种新的阶梯生长机制，即通过阶梯位的串联过程使生长单元从溶液进入扭结位的速度比直接掺入快。结果表明，在串联过程占优势的情况下，发生了动力学平滑，使生长过程中的[110]阶梯结构发生了剧烈的变化，从平衡的粗糙转变为光滑。
The kinetics and structure of an isolated [110] step on a (001) surface of a Kossel crystal is considered in the framework of a self-consistent mean-field approach taking into account first- and second-nearest neighbors' interaction. A new step growth mechanism is suggested and described quantitatively, in which the incorporation of growth units from solution into kink sites by a series process via step sites can be faster than the direct incorporation. We show that under the dominance of series processes kinetic smoothening takes place that results in a drastic change of the [110] step structure from being rough in equilibrium to smooth during growth.
