The residual resistivity and low temperature thermopower of palladium hydrogen alloys

Measurements have been made on the residual resistivity and the thermopower of various palladium-hydrogen alloys, most of which were in the two phase region. It is found that the variation of the resistivity with either hydrogen or deuterium concentration may be explained on the simple basis that the observed resistivity is an appropriate average between the resistivities of the pure alpha and beta phases. A consistent explanation of the variation of the thermopower can only be found if one includes the effects of supersaturation in the discussion. The thermopower results suggest that hydrogen induced S to d electronic scattering does not play an important role in these alloys, contrary to the case of palladium-silver alloys
