Dudzik, E., Norris, A.G., McGrath, R., Charlton, G., Thornton, G., Murphy, B., Turner, Tracy and Norman, D. (1998) Potassium-induced removal of the Ni(100) (2x2)p4g-N reconstruction determined by surface x-ray diffraction. Physical Review B, 58 (19). pp. 12659-12662. ISSN 1098-0121

The “clock” reconstruction of the Ni(100)(2×2)p4g-N system is shown to be removed by potassium adsorption using surface x-ray diffraction measurements. The removal of the reconstruction is discussed in the framework of a simple model of induced surface stresses.
