Ideal polarizable metal-solution processes

Based on the discussion above, it seems evident that a detailed understanding of kinetic processes occurring at semiconductor electrodes requires the determination of the interfacial energetics. Electrostatic models are available that allow calculation of the spatial distributions of potential and charged species from interfacial capacitance vs. applied potential data (23.24). Like metal electrodes, these models can only be applied at ideal polarizable semiconductor-solution interfaces (25)- In accordance with the behavior of the mercury-solution interface, a set of criteria for ideal interfaces is f. The electrode surface is clean or can be readily renewed within the timescale of... [Pg.440]

Most of the events in electrochemistry take place at an interface, and that is why interfacial electrochemistry constitutes the major part of electrochemical science. Relevant interfaces here are the metal-liquid electrolyte (LE), metal-solid electrolyte (SE), semiconductor-electrolyte, and the interface between two immiscible electrolyte solutions (ITIES). These interfaces are chargeable, that is, when the external potential is applied, charge separation of positive and negative charges on the two sides of the contact occurs. Such an interface can accumulate energy and be characterized by electric capacitance, within the range of ideal polarizability beyond which Faraday processes turn on. [Pg.33]
