Direct Analysis of the Structure, Concentration, and Chemical Activity of Surface Atomic Vacancies by Specialized Low-Energy Ion-Scattering Spectroscopy: TiC(001)

Abstract
The structure, concentration, and chemical activity of atomic vacancies at the TiC(001) surface have been directly analyzed by specialized low-energy ion-scattering spectroscopy. It has been found that carbon vacancies are formed at the surface under a certain condition, and they capture oxygen atoms into the vacancy holes exhibiting a very high activity.
