Cyclotron Resonance and Energy Band Structures

Abstract

Cyclotron resonance has been successfully used to determine the effective masses of electrons in semiconductors. However, the cyclotron resonance has played a very important role in understanding the valence band structures of Ge and Si and later led to an accurate determination of the energy band structures. In this chapter first we will describe the cyclotron resonance experiment and its analysis in order to discuss the anisotropy of the electron effective mass and the many valley structures. Second, we will discuss the analysis of the valence band structures by using the k · p perturbation method, which will reveal the importance of the cyclotron resonance experiments.
