Surface structure of thin ice films
摘要
An angular dependent X-ray absorption spectroscopy study of the surface of thin ice films grown on Pt(111) is presented. Using different probing depths together with spectral calculations based on density functional theory, the spectra are interpreted in terms of the structure of surface, subsurface and bulk regions. It is shown that the crystalline ice is terminated with a large abundance of isotropically distributed free O芒芒芒H groups and a distorted subsurface.
