Silver Nanowire Transparent Conductive Electrodes for High-Efficiency III-Nitride Light-Emitting Diodes

摘要: Silver nanowires (AgNWs) have been successfully demonstrated to function as next-generation transparent conductive electrodes (TCEs) in organic semiconductor devices owing their figures of merit, including high optical transmittance, low sheet resistance, flexibility, and low-cost processing. In this article, high-quality, solution-processed AgNWs with an excellent transmittance 96.5% at 450 nm a resistance 11.7 Ω/sq were TCEs inorganic III-nitride LEDs. The transmission line model applied the AgNW contact p-GaN showed that near ohmic specific ~10(-3) Ωcm(2) was obtained. had strong bias-voltage (or current-density) dependence: namely, field-enhanced contact. LEDs fabricated exhibited 56% reduction series 56.5% brighter output power, 67.5% efficiency droop, approximately 30% longer current spreading length compared reference TCEs. addition cost reduction, observed improvements device performance suggest are promising for application TCEs, realise brighter, larger-area, cost-competitive light emitters.
