DISLOCATIONS IN LAMELLAR AND LIQUID-CRYSTAL FILMS - EQUILIBRIUM LOCATION, EDGE PROFILES, AND PHASE-TRANSITIONS

Title: DISLOCATIONS IN LAMELLAR AND LIQUID-CRYSTAL FILMS - EQUILIBRIUM LOCATION, EDGE PROFILES, AND PHASE-TRANSITIONS
Abstract: A continuum theory of dislocations is applied to three different edge profiles in thin diblock copolymer films deposited on a substrate, equilibrium location of the edge dislocation in systems near free surfaces, and nematic-smectic phase in thin freely suspended liquid crystal films. Because of the tension the edge profile at the air/diblock copolymer surface in films is very broad. In semi-infinite lamellar systems with small tension the dislocation is stabilized at a finite distance from surface. In smectic films of thickness D the temperature of the transition for dislocation loops, T(N-A)(D), is proportional to 1/square-root D.
