摘要
We have studied the surface dynamics of Si(001)(2 X 1)-Ge within an adiabatic bond-charge model, the necessary structural and electronic input information coming from a recent ab initio pseudopotential calculation. The phonon spectrum of the Si(001)(2 X 1)-Ge surface is compared in detail with that of the Si(001)(2 X 1) surface presented in a recent bond-charge model study. (C) 1998 Elsevier Science B.V.
