In this study, we demonstrated a p-type and n-type SnO TFTs on flexible polyimide substrate. The fabricated p-type SnO TFT showed a high Ion/Ioff of 5.7, ×,105 and a high μ FEof 10.7 cm2,V-1s-1. Through optimizing the oxygen plasma condition, the n-type channel TFT transfered from prime p-type channel exhibits excellent characteristics, including a high on/off current ratio of 6.6,×,103, a low threshold voltage of-0.13 V, and a very high field-effect mobility of 28 cm2V-1s-1. This proposed low-temperature oxygen plasma treatment shows the potential in simplification of TFT process that can achieve n-type and p-type TFTs under the same device process.
