Abstract

A study of the Fermi surface of arsenic has been made by the methods of geometric resonance and quantum oscillations in the ultrasonic attenuation. Three distinct groups of carriers are observed: two sets of short periods [Δ(1H)∼10-7G-1] and a third long one (∼10-5G-1). The Fermi surface of one of the short-period carriers (small tilt) can be approximated by a three-tilted-ellipsoid scheme having reciprocal effective-mass-tensor elements β11β33EF2=6.65×1026 erg-2, β22EF=2.17×1012 erg-1, β33EF=33.2×1012 erg-1, and θtilt=6°. The second group of fast-period carriers (large tilt) is observed to be approximately ellipsoidal, but is observed only over a limited range of angles. The slow-period carriers are approximately ellipsoidal, but do not fit into an ellipsoid-of-revolution model.
