Here, we extend our 2D model [1] used previously to study the steady state and scaling laws of OECTs [2,3], to include transient effects. Various factors influencing their transient response are studied experimentally and the observed trends are explained with the new 2D model. Based on this analysis, key factors for increasing the speed of OECTs are put forward, leading not only to an improved performance of OECTs, but as well to a better understanding of the physics of OECTs technology.
