Potentiodynamic electrochemical impedance spectroscopy for solid state chemistry

Potentiodynamic electrochemical impedance spectroscopy (PDEIS) employs virtual instruments for probing the interface and gives, in real time and in a single potential scan, the multidimensional spectra that characterise complex impedance of the interface as a function. of frequency and the electrode potential, along with the potentiodynamic voltammogram. The built-in equivalent electric circuit analyser provides semi-automatic extraction of the potential dependencies of the. double layer capacitance, components of Faraday impedance (charge transfer resistance and Warburg impedance) and some additional impedance elements from the impedance spectra extended for the. variable potential. PDEIS has been applied to probe the electrochemical response of metal monolayers and nanostructures on various supports.
