High operational stability of organic field-effect transistors (OFETs) as well as high field-effect charge carrier mobility is important for their practical application. In this study, we found that the evaluation of the operational stability of polymer-based OFETs exhibiting changes in both mobility and threshold voltage during gate-bias stress was significantly affected by the presence of non-negligible contact resistance. This effect becomes pronounced for short-channel and high-mobility OFETs.
