Wafer-scale transfer-free graphene as an ITO replacement for OLEDs

Graphene’s remarkable electronic properties have made it the focus of much attention for use in solid-state electronic devices. However, realisation of commercial devices has been held back by challenges of processing high-quality monolayer graphene at scale. In this work, we use graphene produced in batch wafer scale by metal-organic chemical vapour deposition (MOCVD) as the anode for organic light-emitting diodes (OLEDs). We show that the graphene is quite unaffected by industry-compatible photolithography and that the graphene-based OLEDs perform as well as OLEDs using indium tin oxide (ITO) anodes.
