ABSTRACT: The coupled surface phonon (Fuchs–Kliewer)/plasmon polaritons are studied by means of high resolution electron energy loss spectroscopy (HRELS) on cleaved, clean and oxygen‐covered InSb(110) surfaces. Intensities and energetic positions of the losses can accurately be described by a layer model in which a surface layer with negligible carrier concentration is assumed. For the oxygen‐covered surface this layer is identified as a depletion space charge layer. Thickness and band bending of this depletion layer are determined.
