In this work the density of states close to the Fermi level EF of the Fe(001)-p(1x1)O surface is investigated, by means of scanning tunneling spectroscopy (STS). STS spectra are dominated by two features, located at about 0.5 eV below EF and 0.9 eV above EF. The comparison with ab initio density-functional theory simulations of the surface electronic structure shows a very good agreement and allows assigning the observed features to minority states of the sample surface.

Abstract
In this work the density of states close to the Fermi level EF of the Fe(001)-p(1x1)O surface is investigated, by means of scanning tunneling spectroscopy (STS). STS spectra are dominated by two features, located at about 0.5 eV below EF and 0.9 eV above EF. The comparison with ab initio density-functional theory simulations of the surface electronic structure shows a very good agreement and allows assigning the observed features to minority states of the sample surface.File in questo prodotto:
