Combined Magnetopolaron in Magnetooptical Effects in Quantum Wells
Abstract
Combined polaron states in a rectangular quantum well in a strong magnetic field directed perpendicular to the QW plane have been considered. At low temperatures these states are due to interaction of two electron energy levels (with different Landau quantum numbers (n and n(1)) and different size-quantization quantum numbers (m and m(1)) with confined LO phonons under condition when the energy difference of the electron levels is close to the confined LO phonon energy. The resonant magnetic field H(res). at which a combined polaron forms, depends on the energy difference of the size-quantization levels and consequently depends on QWs parameters. The separation between the branches of the combined polaron energy spectrum Dalta E(res) and H(res) as functions of the QW's width ci have been calculated. It is shown that H(res) may be reduced significantly in comparison to H(res) for the case m=m(1).
