摘要：
By means of Monte Carlo simulations the frozen pattern of a B-type step edge in the Si(100)-(2 x 1) surface is simulated. Sets of two dimers are attached and detached from the step according to the number of nearest and next-nearest neighbors. Average kink length, average kink separation and correlation length from experiments and modeling are presented in order to check the quality of our results. Experimental results are well reproduced by using measured experimental rates. The characteristics of the resulting step profile are also analyzed as a function of the step width.
