A constant wind shear stress is shown to induce roughness on molecularly thin perfluoropolyether films that are susceptible to dewetting. These wind-induced roughening or dewetting features are pinned to the silicon substrate surface, indicating that these perfluoropolyethers have a heterogeneous interaction with the surface. These results highlight the role of chemical heterogeneity in nucleating dewetting phenomena. © 2004 American Institute of Physics.
