摘要：

We apply our recent Green's function based STM formalism to study the adsorption of S monomers and clusters on Re(0001). Starting from previous STM experimental data and LEED results, we consider surface relaxations common to the different S structures observed on this system. The role of such relaxations on the final shape of the theoretical STM images is then examined, and we find that the sensitivity of the images to these structural parameters can be considerable in certain cases. The consistency of proposed relaxed models is also confirmed after a theory-experiment comparison of the STM images. (C) 1998 Elsevier Science B.V. All rights reserved.
