摘要

Recent developments in the performance of organic semiconductors are proving that these materials have the potential to make a significant impact in macroelectronics. Fabrication of large-area devices, such as transistor arrays for display backplanes, light-emitting diode arrays, and large-area photovoltaic cells benefit from the possibility of solution processing and patterning on flexible substrates. As organic semiconductors approach commercialization, there is a need to better understand the relationship between charge transport and microstructure, in particular to identify the inherent bottlenecks to charge transport. A common method to investigate the effect of specific micro-structural features on electrical performance is to introduce known or controlled defects. In noncrystalline, glassy polymeric semiconductors, such as poly-9,9'-dioctyl-fluorene-co-bithiophene (F8T2), studies have focused on interchain versus intrachain transport, where anisotropic transport was realized by aligning the backbone of the polymer molecule on rubbed polyimide.
