MoO x has been used for organic semiconductor doping, but it had been considered an inefficient and/or unstable dopant. We report that MoO x can strongly and stably dope carbon nanotubes and graphene. Thermally annealed MoO x-CNT composites can form durable thin film electrodes with sheet resistances of 100 ω/sq at 85% transmittance plain and 85 ω/sq at 83% transmittance with a PEDOT:PSS adlayer. Sheet resistances change less than 10% over 20 days in ambient and less than 2% with overnight heating to 300 °C in air. The MoO x can be easily deposited either by thermal evaporation or from solution-based precursors. Excellent stability coupled with high conductivity makes MoO x-CNT composites extremely attractive candidates for practical transparent electrodes. © 2012 American Chemical Society.Citation
