摘要：

This letter presents a concept of surface kinetic barrier: The step-facet barrier. This concept is demonstrated for two face-centered-cubic metals, aluminum and copper, through molecular statics calculations. Our numerical results show that the step-facet barrier is substantially larger than step-step or diffusion barriers on flat surfaces; true for both metals. Based on the relative magnitudes of kinetic barriers, we discuss implications of the step-facet barrier on surface processing, particularly the step flow. This discussion shows that the kinetic barrier potentially may enable us to pattern nanowires on a metal surface. (C) 2003 American Institute of Physics.
