Modelling of organic field-effect transistors for technology and circuit design

As organic field-effect transistors (OFETs) are preparing to take a key role in the flexible and low cost electronics applications, there is a pressing need for predictive device models to support technology optimization and circuit design. This paper focuses on the specific OFET features that challenge current modelling approaches. The presented modelling techniques range from the fundamental semiconductor equations to compact device model representations as required for implementation in advanced TCAD and EDA commercial tools. The models are verified with measured characteristics of advanced OFET device structures.
