The surface properties of TiC(001) and TiC(111) surfaces

The surface properties of the TiC(001) and TiC(111) surfaces such as atomic structure, electronic structure and chemisorption were investigated using low energy electron diffraction, angle-resolved X-ray photoelectron spectroscopy, angle-resolved UV photoelectron spectroscopy and ionscattering spectroscopy. The TiC(001) surface has a 1 × 1 structure with a nearly stoichiometric chemical composition, and the chemisorption is very similar to that of platinum. In contrast, the topmost layer of the TiC(111) surface with a 1 × 1 structure consists of titanium atoms, and its chemisorption resembles that of titanium.
