Conduction mechanism based model of organic field effect transistor structure

Carriers mobility model of olygomer and polymer semiconductor based OFET (Organic Field Effect Transistor) structures is presented in this paper. Starting from the conduction mechanism in the mentioned organic materials, a carrier mobility dependence on temperature, electric field and trap density mu(T,E,N-T) was investigated, inspiring directly the current-voltage I(V) model of OFET structures. Subsequent simulations were also performed and the obtained results compared with the data available in the literature
