Si(100) surface states: A success for the (2 × 1) asymmetric dimer model Academic Article uri icon


  • Chadi's asymmetric dimer model of the Si(100)-(2 × 1) surface reconstruction has been reported to yield surface-state dispersion curves in serious disagreement with angle-resolved photoemission measurements. We find that this disagreement is removed when the calculations are performed with an improved sp3s* model of the electronic structure. The asymmetric dimer model thus appears to be quite compatible with experiment. © 1982 The American Physical Society.
