## Abstract The morphology of a thin film was studied for a binary mixture of asymmetric PS‐__b__‐PMMA block copolymers on a flat silicon wafer coated with 50 nm thick silicon oxide. AFM and TEM reveal that the PMMA cylinders orient perpendicular to the substrate by tuning the film thickness. Furth
