The short-range surface potential is determined from the measured temperature evolution of the wetting film. The thermal fluctuations are shown to be insufficient to induce a noticeable breakdown of mean-field behavior, expected in short-range-interacting systems due to their dᵤ=3 upper critical dimensionality.en1079-7114Physical review letters20023American Physical SocietyPhysics - Statistical MechanicsPhysics - Statistical MechanicsPhysics - Materials SciencePhysikTetra point wetting at the free surface of liquid Ga-BiJournal Article10.1103/PhysRevLett.89.0355020205506v1Other
