Show Abstract
In this paper, we investigate the spin-resolved electronic states and spin polarization of the benzene adsorbed Fe(100) surface using density functional theory. The existence of the adsorbate-induced π* state and backdonation of the electrons have been demonstrated clearly by the differential charge densities. The calculated plane-averaged density of states of benzene∕Fe(100) in the vacuum side is found to be consistent with the experimental result of spin asymmetry in the spin-polarized metastable-atom deexcitation spectra for pentacene consisting of five benzene rings adsorbed Fe(100) surface.
