Drag thermoelectric power of uniaxially deformed n-type Ge in quantizing magnetic fields

An investigation is made into the drag thermoelectric power of pure n-type Ge deformed strongly along [111] in quantizing magnetic fields for the phonon-phonon relaxation mechanisms of Herring and Simons. Calculations are made for a wide range of magnetic fields from classical strong fields to maximal quantizing fields, including the region of so-called weak quantization. An experiment is suggested that could indicate the mechanism of phonon-phonon relaxation.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 10, pp. 66–70, October, 1980.We thank Professor A.
