THE THERMOELECTRIC POWER OF V3X COMPOUNDS

Abstract

The thermoelectric powers of the intermetallic compounds V₃Ge, V₃Si, V₃Ga, and V₃Sn have been measured from their superconducting transition temperatures to room temperature. It is found that the thermoelectric coefficients are all positive and about 10 μv/° K at room temperature. The coefficients for V₃Si, V₃Ga, and V₃Sn are monotonically increasing functions of the temperature, whereas for V₃Ge there is a pronounced maximum at about 60° K. The results are discussed in terms of a two-band model consisting of a conduction band and a d-band.
