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. © 1968 The American Physical Society.
