Porous Organic Field-Effect Transistors for Enhanced Chemical Sensing Performances
TL;DR: In this article, it has been demonstrated that OFET ammonia sensors with porous OSC films can be fabricated by a simple vacuum freeze-drying template method, and the resulted devices can have ammonia sensitivity not only much higher than the pristine OFETs with thin-film structure but also better than any previously reported OFET sensors, to the best of their knowledge.
