Pushing the conductance and transparency limit of monolayer graphene electrodes for flexible organic light-emitting diodes.

ABSTRACT: Graphene has emerged as an attractive candidate for flexible transparent electrode (FTE) for a new generation of flexible optoelectronics. Despite tremendous potential and broad earlier interest, the promise of graphene FTE has been plagued by the intrinsic trade-off between electrical conductance and transparency with a figure of merit (σ_DC/σ_Op) considerably lower than that of the state-of-the-art ITO electrodes (σ_DC/σ_Op <123 for graphene vs. ∼240 for ITO). Here we report a synergistic electrical/optical modulation strategy to simultaneously boost the conductance and transparency. We show that a tetrakis(pentafluorophenyl)boric acid (HTB) coating can function as highly effective hole doping layer to increase the conductance of monolayer graphene
