Graphene on quartz modified with rhenium oxide as a semitransparent electrode for organic electronics

The presented research shows that commercially available graphene on quartz modified with rhenium oxide meets the requirements for its use as a conductive and transparent anode in optoelectronic devices. The cluster growth of rhenium oxide enables an increase in the work function of graphene by 1.3 eV up to 5.2 eV, which guarantees an appropriate adjustment to the energy levels of organic semiconductors used in organic light-emitting diode devices.
