The Thermopower and the Thermomagnetic Power in Arsenic—Antimony Alloys at Low Temperature

The thermopower and the thermomagnetic power at low temperatures (4.5 to 77 K) is investigated in As x Sb 1‐ x ( x ⩽ 0.3) alloys. Peculiarities of the thermopower are observed, which are associated with the dragging of electrons by phonons. In magnetic fields B > 5 T the Shubnikovde Haas type quantum oscillation of the thermomagnetic power is displaid. It is established, that the As x Sb 1‐ x ( x ⩽ 0.2) alloys are semimetals, and the overlapping of the energy extrema of L electrons and H holes increases, when arsenic is added to alloys.
