High temperature impedance measurements on Au microelectrodes deposited on polished yttria stabilized zirconia (YSZ) pellets were demonstrated using a newly designed controlled atmosphere high temperature scanning probe microscope (CAHT-SPM). Probes based on Pt0.8Ir0.2 were fabricated and employed in all the investigations. The electrical properties of the Au microelectrodes were investigated using CAHT-SPM at various temperatures in air. The influences of the tip-sample force and of the size of the microelectrode on the electrical properties of the Au microelectrodes were also studied. The impedance spectra of circular Au microelectrodes down to 8 μm in diameter at different temperatures were successfully obtained. The CAHT-SPM presented in this paper is capable of obtaining topography images, conductivity images and impedance spectra in-situ in a temperature range from room temperature to at least 650 °C.
► CAHT-SPM for in-situ study of microelectrodes at high temperature.
► Electrical properties of Au microelectrodes on yttria stabilized zirconia.
► Topograhy, conductivity, and impedance spectra up to 650 °C.
