Abstract
An experimental and theoretical evidence that the electron-impurity sc attering is modified in the presence of the electromagnetic field osci llating with the frequency corresponding to the optical phonon energy is given. The coupled plasmon-phonon mode related feature in the refle ctivity spectrum can be used to determine the upper edge of the LO pho non frequency band in highly doped materials.
