We propose a simple process to obtain high-performance thin-film transistors (TFTs), namely hydrogenated polycrystalline In2O3 (In2O3:H) TFTs grown via the low-temperature solid-phase crystallization (SPC) process. In2O3:H TFTs fabricated at 300 °C exhibit superior switching properties with field-effect mobility of 139.2 cm2V−1s−1, a subthreshold swing of 0.19 Vdec−1, and a threshold voltage of 0.2 V.
