Abstract
The surface layer structure of ice can be strongly affected by the surface boundary condition. M. Faraday first suggested in 1850 that, even below the freezing temperature, there might exist a thin film of water at the vapor/ice interface. This surface melting phenomenon has been experimentally proven in recent years by various techniques, although quantitative characterization of the phenomenon is still in disarray. Surface melting is, generally speaking, the result of surface-induced disordering. We discuss here the surface-induced effect on ice by a fused quartz substrate and by a Pt( 111) substrate.
