✦ Synopsis
The impedance corresponding to charge transfer and storage at p-GaAs electrodes provided with electrodeposited gold is calculated and compared to results of measurements in various electrolyte solutions. It is concluded that the results are in good agreement with the predictions based on a model in which the interactions between gold-related surface states and both the valence band and an oxidizing agent in the electrolyte solution play a central role.
