X-ray reflectivity study of temperature-dependent surface layering in liquid Hg. Physical Review B 58(20): R13419–R13422.1098-0121http://nrs.harvard.edu/urn-3:HUL.InstRepos:4419624We report x-ray reflectivity measurements of liquid mercury between -36 °C and +25 °C. The surface structure can be described by a layered density profile convolved with a thermal roughness σT. The layering has a spacing of 2.72 Å and an exponential decay length of 5.0 Å. Surprisingly, σT is found to increase considerably faster with temperature than the √T behavior predicted by capillary wave theory, in contrast with previous measurements on Ga and dielectric liquids.en-USJournal Article10.1103/PhysRevB.58.R13419
