POSS-based photo-curable insulating materials for organic thin film transistors |
| 초록 |
Organic field-effect transistors (OFETs) consist of a gate insulator and an organic semiconductor. In recent years, performances of organic semiconductors have been improved considerably, but insulating materials are still a weak link in OFETs. Here we synthesized polyhedral oligomeric silsesquioxane (POSS)-based photo-curable insulating materials with acryl functional groups. The synthesized insulators were cross-linked and solidified under UV irradiation in presence of a selected photo radical initiators. We fabricated MIM device of ITO/insulator/Au to measure electrical properties such as leakage current and capacitance of the materials. We also fabricated an organic thin film transistor (OTFT) using pentacene as an active p-type organic semiconductor and the synthesized insulator as a gate dielectric layer. Properties of insulating materials and device characteristics of OTFTs will be presented. |
