AFM study of Gibbs films of semifluorinated alkanes at liquid crystal/air interfaces. 
Forming micelles: The first in situ AFM study of Gibbs films of semifluorinated alkanes at liquid crystal/air interfaces is presented.  The Gibbs films self-organize in a hexagonal close packing of surface micelles with shapes and lateral dimensions that are similar to micelles forming on aqueous and solid surfaces.  It is concluded that he formation of surfaces micelles and their self-organization in large-area dense hexagonal arrays are intrinsic properties of semifluorinated alkane molecules.
