摘要：

Ca3Co4O9 thin films synthesized through solution processing are shown to be high-performing, p-type transparent conducting oxides (TCOs). The synthesis method is a cost-effective and scalable process that consists of sol-gel chemistry, spin coating, and heat treatments. The process parameters can be varied to produce TCO thin films with sheet resistance as low as 5.7 k Omega/sq (rho approximate to 57 m Omega cm) or with average visible range transparency as high as 67%. The most conductive Ca3Co4O9 TCO thin film has near infrared region optical transmission as high as 85%. The figure of merit (FOM) for the top-performing Ca3Co4O9 thin film (151 M Omega(-1)) is higher than FOM values reported in the literature for all other solution processed, p-type TCO thin films and higher than most others prepared by physical vapor deposition and chemical vapor deposition. Transparent conductivity in misfit layered oxides presents new opportunities for TCO compositions. (C) 2014 AIP Publishing LLC.
