The presence of a surface charge and a compensating Debye-Huckel layer of charged point defects in ionic crystals was suggested by Lehovec. The surface charge was later associated with charged surface entities. Indirect evidence from sublimation measurements supported such a view, but direct evidence was lacking. In the present work, the direct effect of an externally applied electrostatic field on the topography of monomolecular ledges was determined for sublimated alkali halide surfaces decorated with gold. The changes of shape of the ledges produced by the field show the presence of charged kinks on the surface.
