A model for carburised W(100) and W(110)

Abstract
Using LEED and AES the surface phases induced on W(100) and W(110) by carbon have been re-examined. A surface carbide, W3C2, is proposed for the W(100) and W(110) surfaces containing the most carbon. The conditions for producing the surface carbide on W(110) that contains the least carbon, possibly W9C2 or W4C, have been defined.
