Untersuchungen an Wismutkristallen. II. Änderung der Thermokraft in transversalen Magnetfeldern

Abstract: Mit 11 Figuren) 1. Einleitung. Die folgende Untersuchung schlieI3t an die kiirzlich erschienene uber Warme-und Elektrizitktsleitung (A, x ) von Wismutkristallen in transversalen Magnetfeldern (1) (im folgenden als I zitiert) an. Sie behandelt den ,,2. Ettingshausen-Nernst-Effekt", d. h. die Entstehung einer longitudinalen Potentialdifferenz langs des Warmestroms oder, wie es N e r n s t (2) schon aufgefaBt hat, die h d e r u n g der Thermokraft (Th.-Kr.) des Wismuts oder die Verschiebung des Bi in der thermoel… Show more

“…[11] In the present paper we report measurements of transverse thermopower on a single crystal microwires of bismuth in a glass cover. Like in the case of "Umkehr effect" [12][13][14][15] (unexpected asymmetry in the magneto-Seebeck effect of Bi single crystals under sign reversal of the magnetic field), the transverse thermopower is strongly asymmetric when reversing the temperature gradient.…”

“…For the first time CE has been observed in [2] and later in bismuth crystals [3] in connection with the check of the Kelvin relation (%(B) = T;(--B)). The appearance of the given effect in Bi is related to the peculiarities of its band structure.…”

“…These data have shown that the orientation of the applied magnetic field with respect to its rhombohedral crystal axes plays an important role in optimizing FOM values in Bi,,-,,Sb, alloys. In fact the behavior of the thermopower in a transverse magnetic field for Bi (Gruneisen 1936) and B4,,Sbx (Wove 1963) is very Werent, dependent on the relative orientation of magnetic field and crystallographic axes and is closely related to the crystal symmetry and band structure of these materials. However, little has been published to rationalize physically this fact in terms of a microscopic picture.…”
