Phys. Rev. Lett. 99, 096104 (2007) [4 pages]Partially Wetting Thin Liquid Films: Structure and Dynamics Studied with Coherent X RaysReceived 24 April 2007; published 31 August 2007 We studied the surface structure of thin liquid films vapor deposited on solid substrates in a partial wetting situation by means of coherent x-ray scattering. No dynamics has been observed showing the absence of capillary waves on liquid films partially wetting a substrate. Instead an exponential form of the height-height correlation function has been found pointing toward a solidlike behavior of the thin liquid films at large length scales. The exact surface structure and degree of replication with the substrate depend on the deposition rate of the molecules. © 2007 The American Physical Society URL:
