Description
Electrified interfaces are encountered whenever two different conducting phases come into contact, and they can be defined as those interfaces whose electrical state can be kept under control and varied at will. Electrified interfaces range from metal/semiconductor and metal/electrolyte interfaces to colloidal particles and biological membranes; even metal/vacuum interfaces can be regarded as electrified when their work function is controlled by varying the amount of some chemisorbed species. The role played by electrified interfaces is fundamental in some many physical, chemical and biological system that their study has been tackled by researchers with different scientific backgrounds using different methodological approaches.
