Self-assembled morphologies formed with the variations of D 4/ L L and α for symmetric diblock copolymers confined in channels with square-shaped cross sections. For clarity, the structure of domain B is also shown separately for some special morphologies. For some concentric lamellar structure, a cross section view is also given. When the same type of morphology is formed at a given D 4/ L L but in a range of α values, only these morphologies at the two boundary α values are shown.
