Despite the many advances in the materials and technology of organic transistors, the highest transit frequency reported for organic transistors has not been improved for more than half a decade and remains far below 1 GHz. One reason is that most contributions to the field have traditionally focused on parameters that have little or no impact on the high‐frequency performance of organic transistors. By analyzing the fundamental equations for the transit frequency and the effective (or apparent) carrier mobility, the requirements under which organic transistors can be expected to show a transit frequency of 1 GHz are reiterated. Not surprisingly, it is found that the critical parameter in this quest is not the charge‐carrier mobility in the organic semiconductor layer, but the contact resistance, along with the channel length and the parasitic gate‐to‐contact overlaps.

我们会看到千兆赫有机晶体管吗？
尽管有机晶体管的材料和技术取得了许多进步，但是有机晶体管的最高传输频率在过去的五年多的时间内没有得到改善，并且仍然远远低于1 GHz。原因之一是传统上对该领域的大多数贡献都集中在对有机晶体管的高频性能影响很小或没有影响的参数上。通过分析传输频率和有效（或视在）载流子迁移率的基本方程式，重申了可以预期有机晶体管显示1 GHz传输频率的要求。毫不奇怪，发现此任务中的关键参数不是有机半导体层中的载流子迁移率，而是接触电阻，
