摘要：

STM not only provides information about lateral and vertical distances and the atomic structure in the layer of the adsorbate, it can also be used for site determinations of an adsorbate under favourable conditions, even on a closed packed metal surface without atomic resolution of the bare surface. Using the lateral shifts between the inequivalent terraces A and B of the Ru(0001) surface we show that sulphur, ordered in p(2 x 2) and (square-root 3 x square-root 3)R30-degrees structures, exclusively occupies the hcp threefold site up to a coverage of theta = 1/3.
