Abstract
We discuss resonant scattering by LO phonons in zincblende-type semiconductors. It has an allowed (deformation potential) and a forbidden (Fröhlich interaction) component. For a (001) surface_the scattering amplitude changes sign in going from the [110] to the [110] polarized scattering configurations. The forbidden component, always diagonal, remains the same. Interference between the two components, which can be easily identified by going from the [011] to the [O1l] polarized configurations, takes place. These interference phenomena decrease for impure samples as a result of the incoherent forbidden scattering induced by the impurities. Data for GaAs and InSb are presented.
