Abstract
Theoretical expressions for the conductivity tensors of semimetals are derived using the deformation potential approach and are compared with experimental values for zone-refined bismuth at 20.4°K in fields up to 7000 Oe. The agreement is reasonably satisfactory if one assumes only one light-hole band. The data appear to be quite inconsistent with the existence of an additional heavy-hole band, unless we assume an extremely small deformation potential for the heavy hole. Numerical values for the relaxation times and the deformation potential are derived from the experimental results.
