| Abstract: |
Using a gradient combinatorial approach, the authors report the effects of temperature on the microstructure and hole mobility of poly2,5-bis3-dodecylthiophen-2ylthieno3,2-bthiophene thin films for application in organic field-effect transistors. The gradient heating revealed a detailed dependence on thermal history. Optimal heat treatment achieved mobilities as high as 0.3 cm2 V−1 s−1. Mobility enhancement coincides with an increase in crystal domain size and orientation, all of which occur abruptly at a temperature closely corresponding to a bulk liquid crystal phase transition. |
