On the origin of the variation of the binding energy shifts of core levels between surface and bulk atoms in transition metals

We present here a model in which the change of the binding energy of core levels at the surface is due to the displacement of the d dand which arises from the narrowing of the surface density of d states. We predict a change of sign of the surface modification of the core level energy shifts near th...

Description
Summary:We present here a model in which the change of the binding energy of core levels at the surface is due to the displacement of the d dand which arises from the narrowing of the surface density of d states. We predict a change of sign of the surface modification of the core level energy shifts near the middle of the d series (i.e. between Ta and W in the 5d series). Finally, chemisorption effects are discussed.
