title: Microsecond Response in Organic Electrochemical Transistors: Exceeding the Ionic Speed Limit.
abstract: Organic electrochemical transistors (OECTs) are transistors that can have extrinsic transconductances as high as 400 S m-1, but they typically have response times on the order of 1 ms or longer. These response speeds are limited by ion transport. It is shown that OECTs can exceed the ionic response speed by a factor of 30 when operated in a high-speed bias regime.
