A hybrid-phonon resonance in a quasi-two-dimensional nanostructure

The coefficient of absorption of electromagnetic radiation by a quasi-two-dimensional electron gas placed in an oblique magnetic field is found. The scattering of electrons by optical phonons is shown to lead to resonant absorption. The shape of the resonance peaks on the absorption curve is studied, and their doublet nature is demonstrated. Finally, the dependence of the resonance peaks on the angle between the magnetic field vector and the confinement plane is investigated. Zh. éksp. Teor. Fiz. 111, 1092–1106 (March 1997)
