The electrical resistivity of pure Bi, Bi-Sb, Bi-Pb, and Bi-Te alloys at 1.3 < T < 77°K has been measured. For all the systems the ideal resistivity shows a T2-dependence at low temperatures. However, there is a characteristic difference between the compensated (Bi, Bi-Sb) and the uncompensated materials (Bi-Pb, Bi-Te). Several mechanisms, which may account for the data, are discussed.
