摘要
The Si(001)surface is studied by the stab dynamical calculation using Keating model with the inclusion of an anisotropic pair interaction between surface atoms.T=0 phase diagram is obtained by diagonalizing the slab matrix numerically.Detailed information of the S(001)surface reconstructive structure is afforded and to be compared with experiments.
