Ellipsometric techniques for the characterisation of electrode surfaces

The use of ellipsometry in the study of the electrode/electrolyte interface is reviewed within the context of a number of important problems, where these studies have led to real advances in our understanding. The areas covered include the adsorption of organic and bio-organic molecules on electrode surfaces, the growth of reactive films on metals such as zinc and iron, the growth of electroactive organic and inorganic polymers on electrodes, and the switching of these polymers.
