摘要: Both Si9H12 and Si15H16 cluster models for the Si(100) surface were studied using Hartree–Fock molecular-orbital method density functional theory. Our investigation shows that ground state of consists buckled dimers, contrary to results a number previous embedded calculations, but in agreement with some recent slab calculations. The relaxation constraints used studies probably do not model layers adequately.
