Organic Field-Effect Transistors

The first OFETs were developed during 1980s. Since then, device performance has radically improved, combining with a better understanding of the properties of organic semiconductors. OFETs act as excellent devices for investigation of charge transport in organic semiconductor (OSC) materials. Compared to conventional silicon-based transistors, OFET with conjugated small molecules or polymers can be conveniently fabricated at a low temperature as well as cost. Particularly, polymeric semiconductors for OFETs are mechanically deformable and usually processed through solvents, demonstrating potential for large-area processing of flexible and stretchable electronics, such as integrated circuits, sensors, and light-emitting displays.
