Abstract

The electronic structure of electrode-thermistor interfaces will be related to the thermochemical properties of the interface. Sessile drop wetting experiments of metallic electrodes on commercial BaTiO₃ PTCR ceramic devices in combination with measurements of the electrical contact properties of the interface through impedance spectroscopy measurements will be used to establish a fundamental perspective of the electrode-ceramic interface. It will be shown that the thermodynamic work of adhesion (W_ad), which is the sum of the strengths of chemical interactions present at the interface, can be manipulated by the addition of chemically active elements to the electrode metal which can segregate to the interface and enhance adhesion. This same procedure will be used to modify the important electrical interfacial properties such as the contact resistance and capacitance.
