Abstract
The pseudo-parabolic model (Heremans and Hansen, 1979) for the analysis of the thermoelectric power of bismuth in zero and weak magnetic fields is analysed further by calculation of the effect of intermediate and strong, non-quantising magnetic fields. The calculations are performed for elements of the thermoelectric power and of the electronic thermal conductivity. Comparison with experimental data in the range from 20K to room temperature shows that a variety of complicated field dependences in the intermediate field range, previously unexplained, follow from the present analysis. In strong fields a number of disagreements appear. The field values at which the disagreements set in are found to coincide quite well with the Landau quantisation limits.Keywords
