MAGNETO-ACOUSTIC GEOMETRIC RESONANCE STUDY OF BISMUTH UNDER HIGH QL CONDITION.
Abstract
Magneto-acoustic geometric resonance measurements were carried out to 'caliper' the Fermi surface of bismuth under the condition of ql approx. 100. Attenuation oscillations due to the electron surface were observed for most orientations of the magnetic field. No clear oscillations were observed for the hole surface. The results for the extremum momenta fit an ellipsoidal geometry for the Fermi surfaces within 5 percent. The ratios of the inverse effective mass tensor components deduced from this experiment using an ellipsoidal model are alpha-11/alpha-22 = 78.1, alpha-33/alpha-22 = 43.9, alpha-23/alpha-22 = 5.1. The tilt angle calculated from these values if 6.7 degrees. (Author)
