Abstract
Unidirectional alternating (100)-(010) faceting has been observed for the clean TaC(110) surface using both high-resolution low-energy elect ron diffraction and scanning tunneling microscopy. Facets propagate pe riodically along the [110BAR] direction a rid form a ridge-and-valley grating, characterized by an average periodicity of approximately 6 la ttice spacings in the [110BAR] direction, where (110) terraces are com pletely absent. This faceted surface is shown to be an energetically f avored structure.
