Abstract
It is suggested that the 2×1 and 7×7 reconstructions of Si(111) surfaces are inherently quite similar and propose a 7×7 structure based on ringlike arrangements of positively and negatively charged surface atoms. High-resolution angle-resolved photoemission data are shown to provide strong support for the buckled, (2×1)-like nature of the 7×7 surface.Keywords
