Abstract
ABSTRACTWe have modeled the Ni-P amorphous alloy system by a set of supercells on which we have carried out calculations of electronic and transport properties. The thermopower is determined by calculating the energy dependence of the dc electrical conductivity from the Kubo formalism. At 15% P we find -0.015 μV/K2 for the thermopower divided by the temperature, while for 25% P the calculated value is +0.008 μV/K2, in reasonable agreement with experiment, particularly with regard to the change of sign with concentration.
