dc.description.abstract | Although n-type transparent conductors have been commercialized with high optical transmittance and electrical conductivity, the realization of their p-type counterparts has been a challenging problem. Here, we report the synthesis of a highly conductive transparent p-type sulfur-doped CuI (CuI:S) thin film using a liquid-iodination method with a thiol additive. The CuI:S film shows a remarkably high electrical conductivity of 511 S cm-1 with an optical transmittance of greater than 80%. Furthermore, additional hole doping of CuI:S with H2O2 treatment improves the electrical conductivity to 596 S cm-1. Consequently, CuI:S exhibits a record-high figure of merit (FOM) value of 63,000 M C2-1 (73,000 M C2-1 with H2O2 treatment), which is similar to 370% (similar to 430% with H2O2 treatment) higher than the previously reported record high FOM value. The highly conducting CuI:S electrode is successfully applied as transparent conducting electrodes of the organic light-emitting diode and transparent p-type thin-film transistor. The liquid-iodination chemical method with unconventional control of the reaction parameters can be generalized to produce high-quality metal halide thin films, allowing them to be applicable for transparent electronics and optoelectronics. | - |
