摘要: Abstract Using a Hubbard Hamiltonian treated in the Hartree-Fock approximation, it is proposed that (2 × 1) reconstruction of Si(001) stabilized by two-dimensional 2) antiferromagnetic ordering magnetic moments on dimers. This provides consistent explanation semiconducting character surface without invoking any asymmetry These results are agreement with recent work Artacho and Yndurain.
