Compact modeling of organic thin-film transistors

This paper explains the development of a compact model for organic thin film transistors (OTFTs), analyzing some of their features. The model, based on hopping transport between localized states, includes a mobility expression that depends explicitly on both the characteristic temperature and density of states of the distribution of localized states. Temperature dependences are also taken into account. A unified parameter extraction method is also described in detail. The model shows a very good agreement with experimental data from OTFTs of different organic and polymeric materials.
