Abstract
The electrical conductivity and thermoelectric power of liquid tellurium with transition 3d metal impurities were measured in a wide temperature range (from 1700 K to the crystallization temperature) under argon pressure (up to 25 MPa). It is shown that Ti, V, Cr, and Mn impurities decrease the conductivity and slightly increase the thermoelectric power, whereas Fe, Co, Ni, and Cu impurities increase the conductivity and slightly decrease the thermoelectric power. In the region above 1200 K, the thermoelectric power remains virtually constant, whereas the conductivity decreases. The results obtained are interpreted in the context of the model of s-d hybridization. To describe electron scattering in such systems, the Friedel-Anderson procedure is used, based on the ideas about the existence of virtual bound states.
