Notes:
The TiC(001) surface has been observed by scanning tunneling microscopy with atomic resolution in ultrahigh vacuum. After the sample was cleaned by repeated heating at ∼1300 °C, we observed the 1×1 structure. On the other hand, the (square root of 2)×(square root of 2) structure due to the ordered carbon vacancies formed when the sample was annealed at ∼1150 °C. We demonstrated the chemical activity of carbon vacancies of both structures for oxygen. The TiC(001)-1×1 surface with intentionally increased carbon vacancies and the TiC(001)-(square root of 2)×(square root of 2) surface changed to a defect-free 1×1 structure with a small amount of oxygen, owing to the preferential adsorption of oxygen on the carbon vacancies. © 1999 American Institute of Physics.
