Static and kinetic effect of impurities on instability of shape of crystal

点击翻译按钮获取中文摘要

We studied effects of impurities attached to a surface from theoretical and experimental points of view. We showed that increasing of the diameter of 2-dimensional island-like crystal is caused by impurities. Carrying out Monte Carlo simulation, we studied motions of steps on a vicinal face during bunching induced by impurities. We also showed the possiblity of increasing the diffusion coefficient of 2-dimensional island like crystal due to impurities.We tried to study the effect of impurities in solid on behaviors of 2-dimensional island-like crystal, which is caused by long range interaction,and to form an alloy of 2 types of proteins. We cannnot obtain clear conclusioins about The studies, so we continue studying these themes.
