Abstract

The work function of yttria-doped (10 mol%) zirconia was measured at room temperature as a function of time during oxidation and reduction. It was observed that the character of the work function changes depends on the applied surface preparation procedure. It was observed that doping the surface with Ca results in a complex mechanism of oxygen reactivity with the zirconia surface involving initial oxygen-induced reconstruction of the overlayer structure and subsequent chemisorption and incorporation of oxygen into the lattice.
