The metal-to-semiconductor transition in ternary ruthenium (IV) oxides: a study by electron spectroscopy
Abstract
The pyrochlore ruthenium (IV) oxides Pb 2 Ru 2 O 7-y , Bi 2 Ru 2 O 7 , Y 2 Ru 2 O 7 and the perovskites SrRuO 3 , CaRuO 3 have been studied by ultraviolet and X-ray photoelectron spectroscopy (UPS and XPS) and by high-resolution electron-energy-loss spectroscopy (HREELS). The presence of a Fermi edge in UPS confirms that, with the exception of Y 2 Ru 2 O 7 , these materials are metallic; the density of states at the Fermi energy g( epsilon F ) decreases in the sequence Pb 2 Ru 2 O 7-y >Bi 2 Ru 2 O 7 >SrRuO 3 >CaRuO 3 . The probability of reaching final states in XPS where a Ru:3d core hole is screened by conduction electrons decreases in the same sequence, and for Y 2 Ru 2 O 7 only unscreened final states are observed. In parallel with these trends, the conduction-electron plasmon loss found in HREELS moves to lower energy with decreasing g( epsilon F ); plasmon excitation is not evident in the energy-loss spectrum of semiconducting Y 2 Ru 2 O 7 . The results are consistent with a progressive decrease in the transfer-energy (resonance) integral that determines the Ru:4d bandwidth in the series Pb 2 Ru 2 O 7-y >Bi 2 Ru 2 O 7 >SrRuO 3 >CaRuO 3 >Y 2 Ru 2 O 7 , and with a transition to non-metallic behaviour due to correlation-induced electron localisation in Y 2 Ru 2 O 7 . A technique for the calculation of the width of photoemission lines in UPS from HREELS data is presented.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
