title: Design rules for highly transparent electrodes using dielectric constant matching of metal oxide with Ag film in optoelectronic devices.
abstract: Using dielectric-constant (ε) matching of metal-oxide (MO) with Ag film, highly transparent MO/Ag electrodes are demonstrated. At the large-ε MO/Ag interface, surface-plasmon was suppressed and the film showed increased optical-transmittance (>70%). OLEDs fabricated using large-ε MO/Ag electrodes show 1.38 times greater luminance than that of devices with small-ε MO/Ag.
