【 摘 要 】

Magnetophonon resonances are found for omega(c)= omega(LO)/N with N=1,2,3... in the polaron cyclotron resonance (CR) linewidth and effective mass of bulk polar semiconductors. The CR mass and the linewidth are obtained from the full polaron magneto-optical absorption spectrum which are calculated using the memory function technique. The amplitude of the resonant peak in the linewidth can be described by exponential law at low temperature. [S0163-1829(99)09139-0].
