摘要: Total-energy and core-level-shift calculations in clusters of atoms a simple model strongly support symmetric configuration the dimers at Si(100)-2\ifmmode\times\else\texttimes\fi{}1 surface. The spin arrangement within dimer is found to be antiferromagnetic lowering total energy opening gap surface bands. Different experimental results are examined fully compatible with this model.
