제목 Bias-Stress-Induced Charge Trapping in Organic Transistors–A Molecular Structure Perspective
초록 Operational instability of organic field-effect transistors (OFETs) is one of the most critical obstacles to their practical use and commercialization. Prolonged operation of OFETs under an applied bias can cause a significant drop in the channel current and a continuous shift in the threshold voltage, which prohibit the normal operation of an electronic device. The bias-stress-driven electrical instabilities are attributed to charge carrier trapping inside the device. In this talk I will discuss the challenges and our progresses in understanding of charge trapping phenomena in OFETs. Especially, I will overview the recently reported polymer semiconductors with high charge mobility yet low crystalline ordering, and present our recent results on bias-stress induced charge trapping for this type of polymer semiconductors.
