Plasmonic Chromatic Electrode with Low Resistivity.

We report on the optical and electrical properties of a novel plasmonic chromatic electrode (PCE). The PCE was composed of a metallic nano-hole array and ITO layer as a dielectric for electrical property. The structure design was optimized to obtain the matched condition between surface plasmon modes at the top and bottom metal-dielectric interfaces for high transmittance. The fabricated PCEs have high transmittance of 25~40% and low resistivity (level of 10-5 Ωcm) compared to conventional electrodes. Due to the multi-functionality and simple structure of PCEs, we predict the PCEs can be applied for advanced industrial use such as, high resolution, flexible, and stretchable devices.
