ON THE ELECTROCHEMICAL RESPONSE OF ROUGH ELECTRODES .1. THE CURRENT TRANSIENT FOLLOWING A VOLTAGE STEP IN THE ABSENCE OF FARADAIC PROCESSES

For a rough solid electrode the current response to a voltage step in the absence of a faradaic process is described analytically. At short times t, the transient response is expressed by a power series in tα, where α is the interfacial roughness parameter. At long times, the response is expressed by an asymptotic series in t-α. © 1990.
