Post-depostion Binary Solvent Exposure for Improving the Structural Ordering and Electrical Characteristics of Polythiophene Thin Films |
| 초록 |
We developed a facile post deposition method using direct solvent exposure for high performance organic transistor. The morphological, optical, and electrical properties of poly(3-hexylthiophene) (P3HT) films were profoundly influenced by solubility of solvent. Especially exposing to optimized binary solvent mixture of methylene chloride and toluene efficiently improved the morphology and the molecular ordering of a conjugated polymer thin film. Concomitant with the improved order, one finds that the charge carrier transport increases in field-effect transistors (FETs). The correlation between the thin-film structural features and the electrical properties provides the appropriate mixing ratio of a binary solvent and how it influences electronic properties. |
