Abstract

Intraminiband absorption of light by electrons in a quantum superlattice in a quantizing electric field is investigated theoretically taking into account the electron-phonon interaction. It is assumed that the interaction with optical dispersion-free phonons makes the main contribution to electron scattering. It is shown that the point ω=ω0 (ω is the light frequency, and ω0 is the optical phonon frequency) conditionally divides the ω dependence of the absorption into two parts: ω<ω0, the region of exponentially weak absorption and ω>ω0, the region of “strong” absorption. An electric field shifts the region of strong absorption in the red direction of the spectrum.
