摘要：

We have observed the surface structure of (411)A GaAs by atomically resolved scanning tunneling microscopy for the first time. A highly ordered structure of straight atomic rows stretching along the [01 $$($) over bar 1] direction was observed. The structure was found to be composed of two kinds of alternately arranged rows with different contrasts. From this image, a surface structure model was proposed. It was also indicated that the surface roughness of a (411)A surface must be smaller than that of a (100) surface due to the corrugated surface structure in the former case.
