摘要: Of the relaxed, graphitic, buckled, and $\ensuremath{\pi}$-bonded-chain-type models for diamond (111)-(2 \ifmmode\times\else\texttimes\fi{} 1) surface, only chain model appears to account measured surface-band dispersion. The interaction of dangling orbitals which determines dispersion is large in because this are bonds located on nearest-neighbor atoms. data also suggest a dimerization chains.
