Dudzik, E., Norris, A.G., McGrath, R., Charlton, G., Thornton, G., Murphy, B., Turner, Tracy and Norman, D. (1999) The Ni(100)(2×2)p4g–N reconstruction determined by surface X-ray diffraction. Surface Science, 433-45. pp. 317-321. ISSN 0039-6028

The ‘clock’ reconstruction of the Ni(100)(2×2)p4g–N system has been measured using surface X-ray diffraction. An in-plane displacement of the surface layer Ni atoms of dxy=0.30±0.01 Å was found. This value is smaller than that measured for this system using photoelectron diffraction (PED) and surface extended X-ray absorption fine structure (SEXAFS). Possible reasons for this are discussed.
