Publication number: 20160268479Abstract: The present invention relates to a multi-layered transparent electrode having a metal nano hole pattern layer. The multi-layered transparent electrode may include a lower oxide layer, a metal nano hole pattern layer disposed on the lower oxide layer, and an upper oxide layer disposed on the metal nano hole pattern layer. By adjusting the pattern period and nano hole size of the metal nano hole pattern layer, transmittance of the multi-layered transparent electrode may be enhanced in a specific wavelength region through surface plasmon, which is a phenomena caused by the metal nanohole pattern layer. In addition, optimized sheet resistance may be implemented in a multi-layered transparent electrode having the metal nano hole pattern layer by adjusting the hole size. Thereby, electrical characteristics of a device employed the multi-layered transparent electrode may be enhanced.Type: ApplicationFiled: December 29, 2015Publication date: September 15, 2016Inventors: Seong-Ju Park, Sun-hye Song, Sang-Hyun Hong, Hyo-Ju Lee, Jang-Won Kang, Chang-Hee Cho, Bo-Kyung Song
