“…The fitting parameters are alphan. caug, alphap.caug, betan.caug, betap.caug, gamman.caug, gammap.caug, deltan.caug and deltap.caug whereas ncritn.caug and ncritp.caug are the critical doping densities (cm -3 ) for electrons and holes, respectively above which ionized impurity scattering becomes dominant (Menon et al, 2008a). The mobility data has been fit to Eqs.…”
