Abstract
The resistivity and the thermopower of pure antimony have been measured. The electronic transport properties of antimony can be calculated using the extended Ziman formalism. In this formalism the absolute thermoelectric power is negative, while we found that the experimental one is positive.Antimony is a semi-metal. Hafner et al. [J. Hafner and W. Jank. Phys. Rev. B45 6 2739 (1992)] calculated its density of states and showed that it splits into an s and a p band very far from the picture of a free electron band. Taking into account the real density of states, we proposed, for the first time to our knowledge, a "modified extended Ziman formula" which is able to explain the positive thermopower of antimony and its order of magnitude.
