Anisotropy of Magnetoacoustic Attenuation and Deformation Potential in Bismuth

The tensor components Cᵢₖ of the deformation potential for electrons and holes in bismuth were evaluated from the anisotropy of quantum oscillations in the magnetoacoustic attenuation, measured at a frequency $f=60$ MHz and a temperature T=1.6^∘K. The sign of the deformation potential cannot be determined by this method. The present results confirm the piezogalvanomagnetic measurements of Jain and Jaggi and, in addition to these, yield the shear components. The results are (a) deformation potential for principal electron ellipsoid: C₁₁C₂₂=-0.37, C₃₃C₂₂=-0.29, C₂₃C₂₂=+0.25, and C₂₂=±5.9 eV, and (b) deformation potential for hole ellipsoid: C₃₃C₂₂=-1.03 and C₃₃=±1.2 eV.
