摘要：

C-60 forms nonequilibrium disordered islands on the Si(110) surface which progressively decay over several weeks. Over the same period ordered islands with a minimum height of three monolayers are observed to grow. This process has been monitored using an ultrahigh vacuum scanning tunneling microscope operating at room temperature. We discuss these observations in terms of the van der Waals interaction between C-60 molecules and argue that the initial formation of the disordered phase is kinetically driven.
