Prediction of a surface state and a related surface insulator-metal transition for the (100) surface of stochiometric EuO.
We calculate the temperature and layer-dependent electronic structure of a 20-layer EuO(100) film using a combination of first-principles and model calculation based on the ferromagnetic Kondo-lattice model. The results suggest the existence of a EuO(100) surface state which can lead to a surface insulator-metal transition.
