A Common Core Model for Junctionless Nanowires and Symmetric Double-Gate FETs

In this paper, we evidence the link between the planar and cylindrical junctionless field effect transistors (JL-FETs) from the electrostatics and current point of view. In particular, we show that an approximate solution of the Poisson–Boltzmann equation for JL nanowires can be mapped on the planar double-gate topology generating only negligible mismatch, meaning that both devices can share the same core model as far as long channels are considered. These preliminary results are a first step toward a unification of compact models for JL-FETs.
