Improved Device Ideality in Aged Organic Transistors

다국어 초록 (Multilingual Abstract)

The origin of ideality improvement in aged dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT) transistors is explored.
High-performance plastic transistors exhibit nontrivial enhancements under ambient conditions, in the light of emergingparameterization scheme that elucidates the linearity of the transfer curves. Unintentional carrier doping in exceptionallystable DNTT molecules is suggested as the major driver of the recovery of an ideal state of the functional devices, thoroughlyinvestigated by analytical decoupling of the channel and contact potentials as well as numerical fi nite-element simulationon parametric interplays.
