Abstract
Abstract An O2-electrode was fabricated using a metal ion implanted SrTiO3 single crystal. The time resolved oxygen exchange rate of ion implanted strontium titanate (SrTiO3) single crystals was studied by means of oxygen solid electrolyte coulometry (OSEC). Transmission electron microscopy (TEM) was performed in order to determine structural changes after ion implantation. Moreover, theoretical modelling based on defect chemistry under equilibrium conditions was applied for determining of effective rate constants. OSEC measurements turn out to be a damage and calibration free method, which was used for the first time in order to characterize kinetic parameters of oxygen exchange on single crystalline surfaces.
