Crystal size modulation of rubrene thin films using UV-cured hydrophobic polymer gate-dielectric |
| 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 analysises allow to explain structure-property relationship of OFETs. Here, we probe organic semiconductor thin films with well-defined spherulitic micro-grains. The growth and size of micro-sized spherulite significantly depend on the thickness of underlying UV-cured polymer gate-dielectrics. As the thicknesses of polymer insulator increase from 20 nm to 230 nm, the size of spherulite grain was increased and then saturated. |
