`Erratum: Interactions between adsorbed Si dimers on Si(001) [Phys. Rev. B54, 1557 (1996)]

Abstract

Due to poor contrast in the original publication, Figs. 4 and 5 are reproduced below to better illustrate the authors' discussion. FIG. 4. Filled ͑a͒ and empty ͑5͒ state image of a twin ͑note that a second twin is formed between the capturing of both images͒. The inset in ͑b͒ shows a schematic drawing of a twin ͑horizontal gray lines indicate new substrate dimer bonds͒. Interactions between three neighboring B dimers ͑c,d͒; the dimer in the middle is indicated with an arrow. Tunneling conditions: 0.4 nA, 1.3 V ͑a͒; 0.4 nA, Ϫ1.0 V ͑b͒; 0.4 nA, 1.5 V ͑c,d͒.FIG. 5. The formation of a cross ͑b͒ from a twin ͑a͒. Filled ͑c͒ and empty ͑d͒ state images of a cross ͑indicated with an arrow͒ and an isolated C dimer ͑inside the circle͒ with a schematic drawing of the cross structure ͑inset͒. Tunneling conditions: 1.1 nA, 1.9 V ͑a,b͒; 1.0 nA, 1.5 V ͑c͒; 1.0 nA, Ϫ1.3 V ͑d͒.
