Abstract

This study reveals the key role of chemical potential and atomic-scale vibration of the nucleant surface in dictating pre-nucleation liquid-layering and heterogenous nucleation. The effect of potential-well depth D_w and vibration strength β¯ _std of the nucleant surface on the layering and nucleation was examined. We found that nucleants with larger D_w and smaller β¯ _std induce more ordered pre-nucleation layers to enhance nucleation, and proposed that D_w and β¯ _std shall be considered when searching for effective nucleants.
