Abstract

A condensing potential (CP) model was established for predicting the geometric structure of two-dimensional (2D) atomic islands on crystal surfaces. To further verify the CP model, statistical molecular dynamics simulations are performed to investigate the trapping adatom process of atomic island steps on Pt (111). According to the detailed analysis on the adatom trapping process, the CP model should be a universal theory to understand the shape of the 2D atomic islands on crystal surfaces.
