Commentary on the effect of relaxation on the electronic-energy-level structure of the Si(111) surface
Abstract
In the preceding Comment, Appelbaum and Hamann have compared our self-consistent-field, Xα, scattered-wave cluster model calculations with some other surface calculations for Si(111). In this paper we briefly review their and our semi-infinite slab calculations with a view to a further understanding of the effect of surface relaxation. We offer a rebuttal to some of the comments made by Appelbaum and Hamann regarding our calculations. © 1976 The American Physical Society.
