Environmentally-friendly and wafer-scale deposition skill for ultra uniform, highly low amount of high-performance polymer thin film transistor arrays. |
| 초록 |
Brand-new copolymer (PDPPBTTSVS) exhibited unprecedented high mobility up to 3 cm2/Vs in optimal state. We developed a novel, cost-effective semiconductor deposition technique which can be characterized as environmental benign process enabled by molecular engineering, reducing the consumption of expensive solute enabled by vertical phase separation and minimizing the amount of solution enabled by our method. Based on non-chlorinated solvents, we developed optimal thin film deposition method that only 10% of PDPPBTTSVS in weight was enough to preserve charge carrier mobility in thin film. Furthermore, by applying our method, we could fabricate ultra-uniform 4 inch semiconductor film only with 40μg of PDPPBTTSVS, which is almost three orders of magnitude lower than that required for conventional spin-coating method. The resulting transistor array deposited excellent performances with extremely narrow spatial distribution and near-zero threshold voltage. |
