Figure 3
The time response of the total electron yield signal, Ie, initially close to equilibrium at 531 eV (the background prior to the O K-edge) when the energy is changed to suddenly changed 533 eV (the O K-edge maximum) after 150 s (I1). Also shown are the extrapolated background signal and the extrapolated background contribution corrected for the change in the graphite signal (Ib), as discussed in §5. The sample is made up of 40 wt% of graphite and 60 wt% of 3 mol% Y2O3–ZrO2. |
