Abstract

We have studied the structure of the (Formula presented) surface and how it is transformed from the original (2×2) surface under Sb-rich conditions, by using scanning tunneling microscopy, Auger electron spectroscopy, and reflection high-energy electron diffraction. In the 2(Formula presented) structure a Sb trimer settles its center on the In vacancy site of the (2×2) surface, and the three In atoms are further missing from it. These missing In atoms are consumed in a way that, while Sb is deposited onto the (2×2) surface at 230 °C, the 2(Formula presented) surface grows along a direction normal to the step edge, increasing the terrace area and causing the step edge to become ragged.
