有机半导体薄膜空间电荷分布对晶体管 性能影响的研究进展

Organic field effect transistors ( OFETs) are the basic components of the next generation of flexible electronics industry, which are bendable, transparent and solution-processible, and gradually begin to be applied to biosensors, flexible display and other fields. However, OFETs still have problems such as small operating current, small transconductance, low switching ratio, and poor air stability, which limits their further development. The performance of OFETs devices is mainly affected by the distribution of charge and current in the conductive channel. If the charge and current distribution in the channel are properly controlled by external means, it is possible to obtain a device with higher performance or new mechanism. The latest progress on this field is reviewed and prospected, which includes the recent result from our group.
