Abstract
Parameter extraction in organic thin film transistors (OTFTs) is a labour intensive task when contact effects are present. In this work, a constrained many-objective evolutionary parameter extraction procedure is used to determine the parameters of a compact model for the current-voltage characteristics of OTFTs that also includes a model for the contacts. This evolutionary procedure ensures that the extracted parameters comply with the physical meaning on which they are based by adding rules in form of optimization objectives and constrains for the different parameters. The evolutionary procedure is applied to experimental output characteristics of OTFTs. Our numerical results show an excellent agreement with the experimental data.
