Highly ordered nanoring arrays formed by template Si-containing triblock terpolymer thin films
Laterally ordered nanorings with a periodicity of 38 nm are produced from the directed self‐assembly of poly(1,1‐dimethylsilacyclobutane)‐block‐polystyrene‐block‐poly(methyl methacrylate) thin films on topographically patterned substrates. Such nanoscale arrays with vertically oriented rings are highly desired in technological applications including memory using magnetic recording, metamaterial, waveguide, etc.
