Abstract
Following on the success of the recent application of holographic LEED to the determination of the three-dimensional atomic geometry of Si adatoms on a SiC(111)p(3×3) surface, which enabled that structure to be solved, we show in this paper that a similar technique allows the direct recovery of the local geometry of adsorbates forming superstructures as small as p(2×2), even in the presence of a local substrate reconstruction.
