Abstract
The experimental evidence that lead to a new model for the scandate cathode is discussed followed by a description of the model itself. In the full paper the equations governing this model will be derived and used to provide quantitative estimates for the semiconductor and surface properties of a top layer scandate cathode using experimental data and the lattice parameters of scandia. The model is applicable to other metal oxides.
