近些年来,有机薄膜场效应晶体管(OTFTs)得到了快速的发展,但是载流子在薄膜中的传输机理以及如何有效地通过控制有机半导体层的形貌来构筑高性能的有机薄膜晶体管器件仍然是当前研究的难点.本文从有机共轭小分子半导体材料出发概述了通过不同的加工方式来优化和改善其薄膜的有序性,从而进一步提高载流子在半导体层的传输特性及其场效应性能,为制备高性能的有机半导体薄膜器件提供了新的视角和途径.
In recent years, organic thin film field effect transistors (OTFTs) have been rapidly developed. However, the transport mechanism of carriers in the thin film and how to effectively form high performance organic thin film transistor devices by controlling the topography of the organic semiconductor layer are still Is the difficult point of current research.In this paper, based on organic conjugated small molecule semiconductor materials, the order of the films is optimized and improved by different processing methods to further improve the carrier transport properties in the semiconductor layer and its field effect Performance, for the preparation of high-performance organic semiconductor thin film devices provide a new perspective and approach.
