Non-free-electron momentum- and thickness-dependent evolution of quantum well states in the Cu/Co/Cu(001)systemPhysical Review B (2006)
We present systematic k-dependent measurements of the Fermi surface and underlying band structure of quantum well states in Cu/Co/Cu001. Compared to bands from normal emission, we find a complicated evolution of “split” quantum well states as a function of the thicknesses of both the copper overlayer and the
cobalt barrier layer. Self-consistent calculations show that the penetration of the quantum well states into the cobalt barrier layer is significant and leads to the observed very non-free-electron behavior of these states.
