Resonance Absorption of Acoustic Waves by Acceptor Holes in Ge under Strong Magnetic Field

Abstract
The peak structures observed in the magnetoacoustic attenuation in p-Ge are ascribed to the resonance absorption by acceptor holes, which is caused by the sublevel crossings due to the second-order Zeeman effect. The anisotropy with respect to the direction of a magnetic field is explained. The behavior of the magnetothermal conductivity, regarded as evidence for the Jahn-Teller effect, can also be explained by our model.
