Abstract
Recently there has been significant interest in manipulating the
self-assembly behavior of block copolymers to obtain structures that
are not observed in the bulk. Here we explore the conditions for which
self-assembly in laterally confined thin block copolymer films results
in tetragonal square arrays of standing up cylinders. More specifically,
we used self-consistent field theory (SCFT) to study the equilibrium
phase behavior of thin films composed of a blend of AB block copoly-
