Oxygen diffusion in Gd-doped mixed oxides

Determination of Oxygen Nonstoichiometry and Diffusivily in Mixed Conducting Oxides by Oxygen Coulometric Titration I. Chemical Diffusion in La085r02CoO3_5

Oxygen coulometric titration has been applied to measure chemical diffusion in La0 45r0 2CoO36 between 700 and 1000°C. The transient current response to a potentiostatic step has been transformed from the time domain to the frequency domain. The equivalent circuit used to fit the resulting impedance data contains the element that describes the finite-length diffusion of oxygen into the sample s...

Spectral functions in doped transition metal oxides

We present experimental photoemission and inverse photoemission spectra of SrTiO3−δ representing electron doped d 0 systems. Photoemission spectra in presence of electron doping exhibit prominent features arising from electron correlation effects, while the inverse photoemssion spectra are dominated by spectral features explainable within single-particle approaches. We show that such a spectral...
