The oxygen deficiency or excess, as reflected in the nonstoichiometry of oxide films, plays a crucial role in their functional properties for applications such as micro solid oxide fuel cells, catalysis, sensors, ferroelectrics, and memristors. High

The effects of strain on the ionic conductivity of rare-earth substituted CeO2 have been extensively studied, but the results have been inconsistent and focused upon the ‘optimised’ conductors such as Gd or Sm substituted CeO2 where defect associ

Understanding and rationally tailoring defect-mediated optical absorption of nondilute oxide solid solutions represents a complex challenge. In this work, we investigate compositions in the SrTiO3–SrFeO2.5 solid solution, departing from the simpler

Highly textured thin films of undoped, Ce-doped, and Sr-doped Pr2CuO4 were synthesized on single crystal YSZ substrates using pulsed laser deposition to investigate their area-specific resistance (ASR) as cathodes in solid-oxide fuel cells (SOFCs). T

Oxygen transport in the mixed ionic–electronic conducting perovskite-oxides SrTi1−yFeyO3−δ (with y = 0.5 and y = 1.0) was studied by oxygen isotope exchange measurements. Experiments were performed on thin-film samples that were grown by Pulse

A self-assembled three phase epitaxial nanocomposite film is grown consisting of ≈3 nm diameter fcc metallic Cu nanorods within square prismatic SrO rocksalt nanopillars in a Sr(Ti,Cu)O3-δ perovskite matrix. Each phase has an epitaxial relation to

The hetero-interfaces between the perovskite (La1−xSrx)CoO3 (LSC113) and the Ruddlesden-Popper (La1−xSrx)2CoO4 (LSC214) phases have recently been reported to exhibit fast oxygen exchange kinetics. Vertically aligned nanocomposite (VAN) structures

Donor doping of the p-type solid oxide fuel cell cathode, Sr(Ti,Fe)O3-δ, with La was pursued to examine the role of minority charge carriers (electrons) on the oxygen exchange rate. Model dense thin film cathodes of (La,Sr)(Ti,Fe)O3-δ were fabricat

In this work, we extend our earlier studies on the model mixed ionic electronic conducting cathode material system SrTi 1 − x Fe x O 3 − x/2 + δ (STF) by examining how the substitution of Ba for Sr in Ba x Sr 1 − x Ti 1 − y Fe y O 3 − y/2
