摘要：

The multilayer relaxations of (3 1 1), (3 3 1) and (2 1 0) surfaces of Ni, Cu, Rh, Pd, Ag, Ir and Pt have been investigated by pseudopotential DFT calculations. Our calculations show a relaxation sequence of - +(...) for the interlayer spacings of all (3 1 1) surfaces and - - + (...) for all (3 3 1) and (2 1 0) surfaces. We also found that the surfaces of Ir and Pt had more significant relaxations than other surfaces. Comparisons with LEED results, where possible, are also made in this paper. (C) 2003 Elsevier B.V.
