The thickness of the wetting layer was controlled by changing the fluorocarbon chemical potential relative to the reservoir through temperature differences $$\Delta$$T. 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 ($$d \sim$$ 7 Å) as well as complete wetting that following the $$d \sim \Delta T^{−1/3}$$ law.
