摘要：

Cyclotron resonance of electrons and holes has been observed in tellurium single crystals at 24 and 70 GHz and at liquid helium temperatures. In pure specimens and at low temperatures the surfaces of constant energy for the holes are well described by 4 prolate ellipsoids of revolution about the c‐axis located near the Brillouin Zone corners. At higher hole energies produced by thermal or optical excitation or by heavily doping the crystals, pairs of these ellipsoidal surfaces degenerate into dumbbell‐shaped surfaces of revolution. The observed isotropic resonance of high mass electrons (m* = 0.75 m0) suggests an indirect gap at low temperatures. Copyright © 1969 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
