Thermopower due to defects in Ni, Pd and Pt

The thermopower induced by tensile plastic deformation at a near-room temperature is measured to determine the change in thermopower per unit dislocation density ΔSd/Nd in nickel (99.98%). The dislocation density is determined indirectly by measurement of the flow stress. The partial-wave method is used to calculate the contribution of dislocations and vacancies to the thermoelectric power of nickel, platinum and palladium. The value ΔSd/Nd calculated for nickel agrees quite satisfactorily with measured ones. These results are the first quantitative estimation of the defect contribution to thermopower of transition metals.
