Summary:A general theory of transport for a band of spherical symmetry in k-space was developed in a prior paper. Using three special functions for the dependence of energy on wave number vector (the parabolic band, the Kane band for energy gap small or large compared to the spin-orbit splitting), the six basic galvano-thermomagnetic transport coefficients (GTMTC) have been determined in terms of specific transport integrals which must be evaluated numerically. Simple analytic expressions for the GTMTC have been obtained in certain limiting cases. It is of special interest that the parametric dependence of the Nernst coefficient on the scattering index is sensitive to the band curvature.
