摘要：
The theory of phonon-assisted cyclotron resonance in quantum wells is given; we consider cases where electrons are scattered by confined LO phonons described by the Huang and Zhu model, Fuchs-Kliewer slab modes, and Ridley's guided mode model. The effect of interface phonon modes on cyclotron resonance is also studied. Extra peaks due to transitions between Landau levels accompanied by emission of confined and interface phonons in the absorption spectrum are predicted. Numerical results for frequency, field, and well-width dependence are given for parameters characteristic of GaAs/AlAs quantum wells.
