To improve the physical verisimilitude of a given effective mass model, we evaluate models of the donor atom's Coulomb potential, in particular considering the effects of a dielectric constant with dynamic response. We present a phenomenological psuedopotential for exchange and correlation effects from the donor's valence electrons. Finally, we include symmetry breaking perturbations, in particular the effect of an electric field upon the donor electron.
