Abstract: The cyclotron resonance of electrons and of holes in Cu 2 O has been observed between 1.2 and 20K using frequencies of 34 and 137 GHz. Electrons have an isotropic polaron mass of (0.99+or-0.03)m 0 where m 0 is the mass of the free electron. Holes have isotropic polaron masses of (0.58+or-0.03)m 0 and (0.69+or-0.04)m 0 , the error bars defining the points of half-height on the observed resonance curves. The authors attribute the electron resonance to the lowest Gamma 1 + ( Gamma 6 + ) minimum of the conduction band and the heavier hole to the uppermost Gamma 7 + hole band. The lighter hole is attributed tentatively to the Gamma 8 + maximum of the hole band. The exciton spectra of Cu 2 O are discussed in terms of these masses.
