Correlation of conductivity and angle integrated valence band photoemission characteristics in single crystal iron perovskites for 300 K < T < 800 K: Comparison of surface and bulk sensitive methods
A. Braun, B. S. Mun, Y. Sun +9
A single crystal monolith of La0.9Sr0.1FeO3 and thin pulsed laser deposited film of La0.8Sr0.2Fe0.8Ni0.2O3 were subject to angle integrated valence band photoemission spectroscopy…
Correlation of high temperature X-ray photoemission spectral features and conductivity of epitaxially strained (La0.8Sr0.2)0.95Ni0.2Fe0.8O3/SrTiO3(110)
A. Braun, X. Zhang, Y. Sun +7
Reversible and irreversible discontinuities at around 573 K and 823 K in the electric conductivity of a strained 175 nm thin film of (La0.8Sr0.2)0.95Ni0.2Fe0.8O3-δ grown by pulsed…
An electron hole doping and soft x-ray spectroscopy study on La1-xSrxFe0.75Ni0.25O3-δ
Selma Erat, Artur Braun, Alejandro Ovalle +4
The conductivity of the electron hole and polaron conductor La1-xSrxFe0.75Ni0.25O3-δ, a potential cathode material for intermediate temperature solid oxide fuel cells, was studied…
Electron hole - phonon interaction and structural changes in La0.9Sr0.1FeO3 by temperature dependent conductivity and valence band photoemission spectros-copy
A. Braun, J. Richter, A. S. Harvey +9
Electric conductivity and structural details of the hole-doped polaron conductor La0.9Sr0.1FeO3 (LSF10) are reported. The conductivity of a single crystal shows an exponential incr…
Direct evidence for electron hole depletion in La0.5Sr0.5FeO3-d upon B-site cation doping
Artur Braun, Defne Bayraktar, Ashley S. Harvey +5
Partial substitution of Fe by Ta in the hole-doped La0.5Sr0.5FeO3 decreases the electric conductivity by up to three orders of magnitude. This decrease is in immediate correlation…
