Abstract

It is shown that in a semiconductor with quantum wells intraband absorption of long-wavelength radiation due to Coulomb interaction of the electrons is possible as a result of band nonparabolicity. Analytical expressions for the absorption are found for the limiting cases of nondegenerate and strongly degenerate, two-dimensional electron, gas. At high carrier densities the absorption due to electron-electron interaction can be much stronger than absorption due to electron-phonon interaction.
