Abstract

The workfunction of graphene was modified using solutionprocessed molybdenum oxide (MoO_x) resulting in efficient charge injection in PLED. After the doping, the sheet resistance of five layer graphene with optical transmittance of ~88 % was as low as ~180 Ω sq^-1. Compared with the pristine graphene, maximum current efficiency was enhanced by 255 %.
