用高纯度 n 型 CdTe 样品观察到磁声子电阻振荡。电阻极值的位置偏离根据 q = 0 纵向光学声子和低频有效质量的频率的已知值预测的磁场。这些偏差在横向方向上达到 13%，在纵向方向上达到 6%，暂时归因于与所有纵向光学模式相互作用（极化子效应）对电子朗道能级的扰动。
Magnetophonon resistance oscillations have been observed with samples of high purity n-type CdTe. The positions of the resistance extrema are shifted away from the magnetic fields predicted from the known values of the frequency of the q = 0 longitudinal optical phonons and of the low-frequency effective mass. These deviations, which amount to 13% in the transverse orientation and to 6% in the longitudinal orientation, are provisionally attributed to the perturbation of the electronic Landau levels by the interaction with all longitudinal optical modes (the polaron effect).
