$mobility-model-arora
The Arora mobility model ([Arora1982]) is used to simulate the doping dependent mobility in Si and takes into account the scattering of the carriers by charged impurity ions which leads to a degradation of the carrier mobility (ionized impurity scattering). This model is temperature dependent.
The total concentration of ionized impurities is given by ND+NA.
Note: We use the nominal dopant concentration as specified in the input file and not the ionized one.
