Cyclotron Resonance in Germanium

Early cyclotron resonance for holes in Ge gave evidence of two resonant peaks associated with the so-called light and heavy holes. Luttinger and Kohn predicted, on the basis of a careful investigation of the theory of degenerate bands, that at low enough temperatures additional peaks should appear. Subsequent experiments confirmed this prediction. In this paper a comparison is made of the cyclotron resonance theory and the experiments of Fletcher, Yaeger, and Merritt. Values of the effective mass constants which best fit the data are found. Resonant peaks additional to those found by Fletcher, Yaeger, and Merritt are predicted and discussed.
