Nanostructures take the color out of thin-film interference between inner interfaces

Nanostructures take the color out of thin-film interference between inner interfaces, Laser Focus World, May 22, 2013.
Inspired (as are many photonics researchers) by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the thin-film interference. This can potentially improve the efficiency of thin-film solar cells and other optoelectronic devices. Chih-Hao Chang, mechanical and aerospace engineering, featured.
