Abstract
The adsorption of pyrrole on and surfaces is studied by means of low-energy electron diffraction and x-ray photoelectron spectroscopy. Accompanying first-principles calculations of energies, geometries, and core-level shifts elucidate possible bonding geometries in dependence on the polarity and the reconstruction of the clean SiC surface. Models for the and phases of surfaces are presented and discussed.
