Carbon nanotube-graphene composite film as transparent conductive electrode for GaN-based light-emitting diodes

Transparent conductive electrodes (TCE) made of carbon nanotube (CNT) and graphene composite for GaN-based light emitting diodes (LED) are presented. The TCE with 533-Ω/� sheet resistance and 88 transmittance were obtained when chemical-vapor-deposition grown graphene was fused across CNT network...

Mohamed, N.M. Ng, T.K. Ooi, B.S. Burhanudin, Z.A. Transparent conductive electrodes (TCE) made of carbon nanotube (CNT) and graphene composite for GaN-based light emitting diodes (LED) are presented. The TCE with 533-Ω/� sheet resistance and 88 transmittance were obtained when chemical-vapor-deposition grown graphene was fused across CNT networks. With an additional 2-nm thin NiOx interlayer between the TCE and top p-GaN layer of the LED, the forward voltage was reduced to 5.12 V at 20-mA injection current. Four-fold improvement in terms of light output power was observed. The improvement can be ascribed to the enhanced lateral current spreading across the hybrid CNT-graphene TCE before injection into the p-GaN layer. © 2016 Author(s).
