Abstract

Polaron cyclotron resonance experiments are performed for high-quality CdTe samples at 4.2 K by use of far-infrared lasers. To study the polaron effect in a magnetic field precisely, various far-infrared wavelengths (513, 419, 394, 295, 220 and 172 microm) are employed on the conditions of photo- and electric field excitations. The polaron mass is obtained as a function of magnetic field for the n=0→n=1 ( n: Landau quantum number) and n=1→n=2 cyclotron resonance transitions. Regarding the n=0→n=1 transition, the experimental results are in good agreement with the theoretical prediction of F. M. Peeters and J.T. Devreese.
