Piezoelectric Polaron-Cyclotron Resonance in the Quantum Limit in n -CdS

This is the authors' abstract. We don't add key points for this paper.

The zero-temperature cyclotron resonance of the electron splits into two groups as the temperature is increased. One group moves rapidly toward very small mass, the other toward larger mass. This splitting has not been predicted by previous theories. Moreover, the first member of the small-mass group can be accounted for only qualitatively by these theories.
