[Wien] Core level shifts

[Lukasz Plucinski]

Dear Wien Users,

I need to calculate core level shifts due to surface. For the surface
valence band dispersions large slabs are necessary. I wonder if I could
get reasonable results for surface core level shifts when using only a
small slab - like 5 or 10 layers.

The related question is how deep core levels I could calculate in this
way? Is it possible fot core level shift at binding energy of around 200
eV? What about E_b around 400 eV?

Is it the parameter 'energy to separate core and valence bands' to be
adjusted?

Regards,

Lukasz
