The self-assembly of block copolymer thin films can generate dense nanoscale patterns over large areas 1,2,3,4,5,6,7,8. When directed by a sparse topographic or chemical template, the block copolymers ...

Through microphase separation, block copolymers (BCPs) can self-assemble into highly uniform, chemically distinct, periodic domains with dimensions and periods at scales of 3–200 nm 1,2 that are ...
