Title: Thinning transitions in free-standing liquid-crystal films as the successive formation of dislocation loops
Abstract: We describe a model for the layer-thinning transition in free-standing films based on the successive, spontaneous formation of loops. As the film temperature increases and the smectic and layer compressional modulus decrease, the condition for a dislocation loop of critical radius is met and a thinning is The resulting equation for N, the number of smectic layers, a function of temperature yields good fitting results to the thinning obtained from several fluorinated compounds.
