Structure of the Electrical Double Layer on HTSC Oxides

4 Structure of the Electrical Double Layer on HTSC Oxides 

The adsorption properties of oxides in electrolyte solutions have been studied in less detail than those of metals. The explanation of these phenomena is based on the model of binding sites which assumes that ions are bound to the hydrated centers which are characterized by acidic- or basic-type dissociation [64,66,71], and also on the electrostatic approach based on the Grahame-Parsons theory [522]. 

The capacitances of the HTSC solution interface cited in the literature [153,523] apparently pertain to the total polarization capacitance. To estimate the double-layer capacitance and more correctly describe the equilibria in the surface layer, the results of -potential measurements can, in principle, be used [423], However, these data correspond to the surfaces which have undergone the degradation.
