For the first time, the authors provide a comprehensive and consistent presentation of all techniques available in this field. They rigorously analyze the behavior of different electrochemical single and multipotential step techniques for electrodes of different geometries and sizes under transient and stationary conditions. The effects of these electrode features in studies of various electrochemical systems (solution systems, electroactive monolayers, and liquid-liquid interfaces) are discussed. Explicit analytical expressions for the current-potential responses are given for all...
