The thickness of the wetting layer was controlled by changing the fluorocarbon chemical potential relative to the reservoir through temperature differences ΔT. The evolution of the microscopic structure of the fluorocarbon layer along the normal-to-surface was measured in situ using X-ray reflectivity. Observed effects include suppression of the SF phase for the thinnest absorbed fluorocarbon layer (d∼7 Å) as well as complete wetting that following the d∼ΔT-1/3 law.en0927-775720021/3293297Elsevier ScienceAlkaneFluorocarbonHydrocarbonSurfaceWettingX-ray reflectivityPhysikConference Paper10.1016/S0927-7757(02)00087-0Conference Paper
