Figure 1. Dependences of electrical conductivity s (a, b), thermopower α (c, d) and Hall RH (e, f) coefficients of extruded samples of the Bi0.85Sb0.15 solid solution on temperature: a, c, e - not passed, b, d, f - heat treated; 1 and 2 unalloyed samples, 3-12 samples doped 0.0001; 0.0005; 0.001; 0.005; 0.1 at.% Te, respectively; 1,3,5,7,9,11 - measurements along the axis, 2,4,6,8,10,12 - perpendicular to the extrusion axis
