Abstract

In quantum-mechanical terms, the cyclotron and electron-spin resonances originate from optical transitions of carriers between the Landau levels and magneticfield-splitted spin sublevels. Measurement of the dependence of the cyclotronresonance frequency on the magnitude and direction of magnetic field provides a direct and reliable way for determining the electron (or hole) effective mass, as well as for studying the nonparabolicity and nonsphericity of an electronic band in a semiconductor. In connection with this, we derive in Sec. 7.1 expressions for the longitudinal and transverse electron mass in a superlattice at the miniband bottom, analyze how the choice of the boundary conditions for the envelopes at the interfaces affects these masses, and discuss the nonparabolicity of the miniband spectrum.
