在频率为34~137 GHz的1.2~20K温度范围内，观察到了Cu2O中电子和空穴的回旋共振。电子的各向同性极化子质量为(0.99+或-0.03)m0，其中m0是自由电子的质量。孔洞的各向同性极化子质量分别为(0.58+或-0.03)m0和(0.69+或-0.04)m0，误差条定义了观测到的共振曲线上的半高点。作者将电子共振归因于导带中最低的伽马1+(伽马6+)，而较重的空穴则归因于最高的伽马7+空穴带。较轻的空穴暂时归因于空穴带的伽马8+极大值。根据这些质量讨论了Cu2O的激子光谱。
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.
