제목 Hybrid graphene films for transparent electrodes in optoelectronic devices
초록   Transparent electrodes commonly take on important roles of widely flowing current with high transparency in optoelectronic devices. In particular, graphene has taken a center stage in one of the next-generation transparent electrodes due to various advantages such as high transparency (~ 95% at 550 nm) and conductivity. However, there is a huge weak point to use a graphene sheet as transparent electrodes alone due to its high sheet resistance, especially as transparent electrodes replacing indium-tin oxide (ITO) for optoelectronic applications such as LEDs.  
  In this work, we have demonstrated a variety of usages of a graphene sheet including a graphene interlayer and Ag-mesh-graphene sheets in GaN-based light emitting diodes (LEDs). Each LED having hybrid graphene films exhibited outstanding performance with excellent electrical and optical characteristics.
