In the last few years, methods that allow manipulating and measuring the spin of electrons have received lot of attention. For instance, in a two-dimensional electron gas spin-split energy bands can appear, because of spin-orbit interaction and asymmetric confinement of the electron gas (Rashba splitting). Recently, we found quantum-size induced giant Rashba splitting for quantum-well states in Pb and Bi overlayers on Cu(111). These quantum-well systems present ideal model systems to further explore the electron and spin structure as a function of quantum-well film thickness. We carried out first time-, angle- and spin-dependent photoemission experiments, which will be presented in this contribution.
