Niobium Surface Segregation in Polycrystalline Niobium-Doped Titanium Dioxide

In the current investigation, Nb surface segregation has been studied in polycrystalline Nb-doped TiO2 (0.65 at %) at two extremes of oxygen activity (p(O2) = 101 kPa and p(O2) = 10–15 Pa) over the temperature range of 1173 to 1673 K. The aim has been to establish the effect of changes in ambient ox...
