Effect of side chain structure in Polyimide Gate Insulators on characteristics of OTFTs |
| 초록 |
Polyimide is one of the popular insulating materials widely used in electronics because of its excellent thermal, mechanical and electrical properties. It is well known that the device performance of organic thin-film transistors (OTFTs) can be controlled by modifying surface properties of a gate insulator. In this study, we have prepared hybrid films from soluble polyimide and polyamic acid solution, and used them as a gate insulator for pentacene OTFTs. The surface properties of the newly prepared hybrid films was controlled by introducing soluble polyimide with nitrile group. The performance of OTFTs with the hybrid films having polar side chain (C-N group) was compared to that of OTFTs with a hybrid film containing non-polar long alkyl side chain (C18 group). We think that the performance can be affected by the morphology of pentacene deposited on both of the polyimide hybrids. It was characterized by atomic force microscopy and x-ray diffraction. |
