      abstract     = {The surface optical or Fuchs-Kliewer phonons of the (0 0 1)
                      surface of 3C-SiC and the Si-terminated (0 0 0 1) surfaces
                      of 4H- and 6H-SiC have been investigated with high
                      resolution electron energy loss spectroscopy (HREELS). For
                      each of the SiC polytypes the frequency of the surface
                      optical phonon changes with surface reconstruction,
                      indicating subtle differences in the static polarization at
                      differently reconstructed surfaces. Due to their anisotropy,
                      hexagonal surfaces exhibit a second, much weaker
                      Fuchs-Kliewer mode. For all surfaces under examination, a
                      linear dispersion of the Fuchs-Kliewer mode frequency has
                      been found for wave vectors close to the Gamma-point. This
                      dispersion can be explained by dynamical dipole coupling
                      between atomic oscillators at the surface of the highly
                      polar silicon carbide. (c) 2006 Elsevier B.V. All rights
