    Abstract

    Copper iodide (CuI) is a p-type transparent conductor that can be synthesized and doped at low temperature (<= 100 degrees C) while maintaining its high-conductivity and high optical transmittance (> 75 %). The realization of such simultaneously high conductivity and transparency makes CuI useful for applications in both active and passive flexible electronics. However, a few of the major disadvantages of CuI include its optical and electronic stability at ambient atmosphere and reduced transparency with iodine doping. In this report, instead of using pure CuI, we fabricate CuI-TiO2 composite thin films which are highly transparent and stable at ambient conditions whilst maintaining degenerate p-type conductivity. The CuI-TiO2 composite film is >80 % transparent (450-2000 nm range), highly conducting (similar to 77 S/cm), heavily doped (> 1.2 x 10(20)/cm(3)), with a mobility of similar to 3.5 cm(2)V(-1)s(-1).
