Abstract

The quantum-mechanical treatment of cyclotron resonance in n -type germanium shows that the nonparabolicity of the conduction band has to be included for a satisfying explanation of experimental results concerning the resonance position and line shape. From the analysis of the temperature dependence of the resonance position it is found that a k·p perturbation theory including the L1 conduction band and the L3′ valence band yields the correct nonparabolicity. Experimental and calculated line shapes agree very well when using electron concentration and relaxation times obtained from Hall effect and mobility measurements.
