Influence of the Contact Effects on the Variation of the Trapped Charge in the Intrinsic Channel of Organic Thin Film Transistors

In this work, we propose a procedure to extract information of the trapping processes that occur in organic thin film transistors (OTFTs) during hysteresis mechanisms. The procedure is based on a compact model that describes the transistor as the combination of an intrinsic transistor and the contact regions. The model is used to extract output characteristics for the intrinsic transistor from experimental measurements. It eliminates the effect …
