Abstract

A physically-based effective mobility model is presented, which includes Coulombic, phonon, and surface roughness scattering mechanisms.  The model is semi-empirical and consists of three physics-based fitting parameters to be extracted with a single measurement of terminal current.  The developed model is shown to be more physical than the commonly-used empirical model, and the doping dependence can be modeled after parameter extraction.  The model has been verified with excellent prediction to the experimental data with broad bias and doping variations.
