Abstract
A self-assembled nanostructure comprises first domains and second domains. The first domains comprise a first block of a block copolymer material and an activatable catalyst. The second domains comprise a second block and substantially without the activatable catalyst. The activatable catalyst is capable of generating catalyst upon application of activation energy, and the generated catalyst is capable of reacting with a metal oxide precursor to provide a metal oxide. A semiconductor structure comprises such self-assembled nanostructure on a substrate.
