Structural precursor to adsorbate-induced reconstruction: C on Ni(100)
UNSPECIFIED. (1999) Structural precursor to adsorbate-induced reconstruction: C on Ni(100). PHYSICAL REVIEW B, 60 (15). pp. 10715-10718. ISSN 0163-1829Full text not available from this repository.
The local structure around adsorbed carbon atoms on Ni(100) has been determined at low coverage as well as in the 0.5 monolayer (2 x 2)p4g ''clock'' reconstruction by scanned energy mode photoelectron diffraction. At low coverage, there is no radial strain of the Ni atoms surrounding the adsorbed carbon, contrary to previous suggestions. None of the C-Ni near-neighbor distances are changed by reconstruction, but the Ni-Ni nearest-neighbor distance in the top layer increases significantly, showing that the adsorbate-induced compressive stress is associated with Ni-Ni, rather than Ni-C, repulsion.
