The structural disorder in sub-microscopic patterns determines various optical properties of device systems. Recently, research on structures with intentionally introduced defects has been actively conducted, including attempts to apply disordered structures to optical devices such as bent plasmonic waveguides. In order to expand the utilization of such disordered structures, reproducible fabrication of structures with controlled degree of disorder is a prerequisite. In this study, we present a methodology for introducing controlled levels of disorder into a single crystalline hexagonal array built on a sphere-forming block copolymer thin film. Here, disordering was induced by the adjustment of annealing temperature, and different trends of disordering were observed depending on the types and the relative amount of metal infiltrated into the core blocks. The results of this study potentially offer a platform for engineering disordered systems for further applications.
