The current-voltage and electroluminescence characteristics of NGR-LEDs with an S-DGE are enhanced remarkably compared to NGR-LEDs with a graphene electrode. The effective current spreading in the whole emission area after thermal annealing of the S-DGE was attributed to reduced sheet and contact resistances caused by the p-type doping of graphene and enhanced adhesion at the graphene-GaN and graphene-silver nanowire interfaces.
