Abstract

A novel combination of an electrochemical quartz crystal microbalance and a scanning electrochemical microscope has been built. The EQCM allows rapid in-situ measurement of the modulus of the crystal's transfer function. Data analysis in the complex plane for the Butterworth-Van Dyke (BVD) equivalent circuit yields the real and the imaginary components R (dampening resistance) and XL (reactive inductance) of the crystal's electroacoustic impedance around its resonance frequency of 10 MHz. If a big change in R is observed during a redox reaction of a non-rigid film, it has been shown previously, that mass changes cannot be distinguished from viscoelastic changes. In this case additional information on ion fluxes across the film/solution interface can be provided by an SECM incorporated into the instrument. This capability is demonstrated with the potentiodynamic deposition and dissolution of a Cu film from a Cu(I) solution.
