Thermoelectric power of hydrogenated amorphous Pd/Si and Ni/P alloys

Thermoelectric power and electrical resistance of amorphous Pd85Si15, and Ni82P18 alloys, charged with hydrogen using high pressure technique. at 0.9 GPa, have been measured in the temperature range between 80 and 300 K. Slight deviations, positive and negative, from proportionality, have been observed in the temperature dependence of thermoelectric power. The increase of hydrogen content leads to increase of both, electrical resistivity and thermoelectric power. The latter changes from negative to positive values. The results are interpreted in terms of the Ziman model. (C) 2002 Elsevier Science B.V. All rights reserved.
