We report a Quartz Crystal Microbalance (QCM) study of the nanotribology of solid and liquid krypton monolayers adsorbed on Cu(111), Ag(111), Ni(111), and C60 substrates at 77.4 K. We document the liquid-solid phase transition and compare the slip times of the krypton for the various substrates. The slip times for the solid krypton monolayers are longer than the slip times for liquid krypton monolayers on metal substrates and monolayer C60 films, as observed previously for krypton/Au(111). However, for bilayer C60 films, the jump in slip time at the liquid-solid phase transition is not present. We discuss these topics and the underlying reasons.
