Grain size control of rubrene thin films using UV-cured hydrophobic polymer insulator |
| 초록 |
Crystallinity of organic semiconductors is well-known to determine the optoelectrical performance of organic field-effect transistor (OFETs). Furthermore, the fabrication of well-defined polycrystalline micro-morphology and its electrical measurements allow to elucidate structure-property relationship of OFETs. Here, we demonstrate organic semiconductor thin films with well-defined spherulitic micro-domains. The growth and size of micro-sized spherulite significantly depend on the thickness of underlying UV-cured polymer insulators. As the thicknesses of polymer insulator increase from 20 nm to 150 nm, the size of spherulite domain was increased and then saturated. Furthermore, the saturation thickness was highly affected by the molecular weight of polymer layer. |
