Professors Kempa and Herczynski co-author a Nature Communication article
Professors Kempa and Herczynski co-author a Nature Communication article proposing a new direction in optoelectronics research, based on Nature's own designs. Titled "Bio-inspired Networks for Optoelectronic Applications," and written in collaboration with researchers in South China Normal University, (Guangzhou, China), the paper shows that using natural structures such as spider webs and leaf venation networks can lead to a new generation of highly efficient solar cells, flexible touch screens, and other devices.
