Abstract
A model for the surface space‐charge layer in thin ionic films has been extended to include the effects of divalent cation impurities and the association of impurity‐cation vacancy complexes. The potential, electrostatic field, and defect distributions are shown to be dependent on film thickness. The fate of photogenerated electrons and holes is discussed relative to the field and defect distributions.Keywords
