Abstract
We report on a semiconducting liquid-crystal polymer (LCP) for organic field-effect transistors (OFET) showing comparable charge carrier mobilities to 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-PEN) on same test structures using organic dielectrics. In addition, we demonstrate a spread reduction of the OFET parameters by using the LCP allowing the fabrication of transistor devices in a simple processing procedure with a high reproducibility compared to TIPS-PEN, which is essential for the functionality of organic integrated circuits. Investigations of the molecular structure of the LCP reveal a high ordering of the molecules even in the liquid phase which further improves after annealing. © 2013 AIP Publishing LLC.
