have succeeded in directly demonstrating the existence of space charge layers at the grain boundaries of YSZ by observing local electric fields using advanced electron microscope. Furthermore ...

The thickness range of the YSZ layer is 1–62 nm. Also included are the data for a single crystal (sc) of YSZ and a thin film (tf), 700 nm thick, with the same nominal composition.

a metal layer of tantalum, and a solid electrolyte called yttria-stabilized zirconia (YSZ) sandwiched between them. Three platinum electrodes control the movement of oxygen ions through this ...
