“…These findings have severe implications. Since real charges are involved, they will play a key role on the position of the CLs, it is clear that initial state effects have to be considered at first, contrary to previous interpretation which relied on final state effects for both Sn adatom p 3 · p 3a phases on Si(1 1 1) [19] and Ge(1 1 1) [13]. In this respect we stress that it is very unlikely that final state effects could reverse the initial state picture [20].…”

“…Calculations performed by Tosatti [18,19,22] correlate the observed charge disproportion of the Sn adatoms, with their surface state occupancy. Two important ideas can be drawn from there:…”

“…The 3 · 3 pattern can result from an arrangement in which one Sn atom is higher than the other two in the unit cell (1U2D), or from the opposite geometry (2U1D). The 1U2D configuration appears the most stable from a theoretical point of view [6,7] and is the one resulting from the analysis of X-ray standing wave measurements [8]. On the other side, other experimental investigations consisting in a doping of the Sn/Ge(1 1 1) surface to assign the two Sn 4d components in the core levels [9], or based on a combination of X-ray standing waves and photoemission [10], lead to favor the 2U1D geometry.…”

“…The exact nature of the transition from fi x fiP phase to (3x3) is not clear, but it may be related to charge density wave instability[l7, 18,19,201 The purpose of this section is to explore the various proposed structural models and other plausible models for Pb coverage between 1/6ML to 4/3ML using first-principles calculations in order to determine the energetically stable Pb coverage and the corresponding energetically favorable geometries. This section is divided into five parts.…”
