Figure 1. Images showing the continuous transition from ordered single-crystal nanostructures (left) to liquid-like disordered nanostructures (right)
The first row shows scanning electron microscopy (SEM) images. The second row presents color-coded maps indicating local alignment of nanoparticles, where dark blue represents highly ordered regions and light yellow indicates disordered regions.
The third row shows analysis results indicating the degree of global structural order: distinct dot patterns correspond to well-ordered structures, while ring-like patterns indicate increasing disorder. (See Fig. 5 in the paper.)
The research team confirmed that by controlling annealing temperature and metal composition within the BCP, the degree of order and disorder in nanostructures can be precisely tuned.

eoul National University College of Engineering announced that a research team led by Professor So Youn Kim of the Department of Chemical and Biological Engineering, in collaboration with Professor Su-Mi Hur’s team at DGIST and Professor S. Joon Kwon’s team at Sungkyunkwan University, has developed a methodology to precisely design and control the “degree of disorder” in nanopattern arrays using metal-infiltrated block copolymer (BCP) thin films*.
* Block copolymer (BCP): A polymer composed of chemically bonded chains of different types of polymers arranged in block structures.
This disordered nanopattern fabrication…
