Oscillatory Magnetostriction in Multivalley Semiconductors: Application top- Type PbTe

Abstract
Magnetostriction oscillations of de Haas—van Alphen origin are observed in p-type PbTe, a single-band multivalley semiconductor. The hole concentration of the material studied is 3×1018 cm3. The amplitude of the oscillations is related not only to the usual shear deformation potential Ξu, which causes intervalley charge transfer as the valleys rigidly shift relative to each other in energy, but also to six strain masses, which describe rotations and distortions of the hole valleys.
