Kinetic Pathways of Order-to-Order Phase Transitions in Block Copolymer Films under an Electric Field

We study kinetic pathways of phase transitions in thin films of block copolymers subjected to an applied electric field by means of dynamic self-consistent-field calculations. We consider structures ranging from spheres to lamellae. We find that the kinetic pathway taken by a system near a phase transition is very different from the one far from a phase transition.
