摘　　要：用远红外激光磁光光谱系统测量了N-Hg_(1-x)Cd_xTe(x≈0.2)的回旋共振,同时用三带模型从理论上计算了样品的朗道能级、电子有效质量和有效g-因子,从回旋共振有效质量的实验值与理论值的比较中获得了带底有效质量及g-因子及其与温度和组份的关系。The far infrared cyclotron resonance in N-Hg_(1-x)Cd_xTe (x≈0.2) was measured with a FIR laser magneto-spectrometer. The Landau levels, the electron effective mass m~* and the effective g-factor g~* were calculated theoretically according to the three-band model. The conduction-band-edge electron effective mass m_0~* and effective g-factor g_0~* were obtained by comparing the theoretical and experimental values of the cyclotron resonance effective mass.
