报告摘要

X-Ray crystal truncation rod (CTR) scattering methods are developed to detect in-situ the pre-nucleation phenomena of liquid Al at the interface with sapphire, which represents a nucleant  substrate for Al. The measured structure factors of the CTR are interpreted to identify the atomic arrangement near the surface. Analysis of the phenomena kinetics reveals the pre nucleation liquid layering to be an adsorption process driven by interfacial energy reduction.
