Professor Shin Jung Hoon’s team from the Department of Physics and the Graduate School of Nanoscience and Technology at the Korean Advanced Institute of Technology (KAIST) produced a display that mimics the structure of the morpho-butterfly’s wings using glass beads.This could be used to make very bright displays with low energy consumption. This new technology can also be utilized for anti-counterfeit bills, as well as coating materials for mobile phones and wallets. The procedure was through the random alignment of differently sized glass beads on a very small scale. This created a disordered substrate, on which they placed a thin periodic film on top using the semiconductor deposition method. This combination of disorder and periodic order created the morpho-butterfly-like structure over a large area.
