Abstract

Electronic structures of the Pb/Si (111) - (√7×√3) surface reconstruction were reexamined using first-principles calculations. The band structures of the proposed models were analyzed in detail. Our results show that the calculated bands for the H3 model at lead coverage of 1.2 ML are in good agreement with the identified bands in the angle-resolved photoemission study. Lastly, the work functions of the √7×√3 and √3×√3 phases were also calculated and compared with experimental measurements. © 2010 The American Physical Society.
