A first principles pseudopotential in the calculation of the phonon limited resistivity of sodium and potassium

E.A. Mendoza , G.J. Vázquez , L.F. Magaña

We have calculated the constant volume and the constant pressure phonon limited resistivity of sodium and potassium using a local, first principles pseudopotential. This kind of pseudopotential has been useful in the calculation of properties of aluminum and lithium. It is obtained from the induced electron density around an ion in the corresponding electron gas. From this pseudopotential we obtained the interionic potential, the phonons (which are calculated by the harmonic approximation) and finally the phonon limited resistivity. The results are in good agreement with experimental results.
