Electronic structure of pristine and Ni-substituted LaFeO from near edge x-ray absorption fine structure experiments and first-principles simulations
Iurii Timrov, Piyush Agrawal, Xinyu Zhang +7
We present a joint theoretical and experimental study of the oxygen -edge spectra for LaFeO and homovalent Ni-substituted LaFeO (LaFeNiO), using fi…
High temperature oxygen NEXAFS valence band spectra and conductivity of LaFe3/4Ni1/4O3 from 300 K to 773 K
Artur Braun, Selma Erat, Ahmad K. Ariffin +4
LaFe3/4Ni1/4O3 was subjected to oxygen near edge x-ray absorption fine structure (NEXAFS) spectroscopy for 300 K < T < 773 K. The spectra show in the pre-edge a small hole doped pe…
Evolution of structural properties of iron oxide nano particles during temperature treatment from 250°C - 900°C: X-ray diffraction and Fe K-shell pre-edge X-ray absorption study
Debajeet K. Bora, Artur Braun, Selma Erat +3
Iron oxide nano particles with nominal Fe2O3 stoichiometry were synthesized by a wet, soft chemical method with the heat treatment temperatures from 250°C to 900°C in air. The vari…
Evolution of an oxygen NEXAFS transition in the upper Hubbard band in α-Fe2O3 upon electrochemical oxidation
Debajeet K. Bora, Artur Braun, Selma Erat +6
Electrochemical oxidation of hematite (α-Fe2O3) nano-particulate films at 600 mV vs. Ag+/AgCl reference in KOH electrolyte forms a species at the hematite surface which causes a ne…
Fe-resonant valence band photoemission and oxygen NEXAFS study on La1-xSrxFe0.75Ni0.25O3-δ
Selma Erat, Hiroki Wadati, Funda Aksoy +4
Iron resonant valance band photoemission spectra of Sr substituted LaFe0.75Ni0.25 O3-δ have been recorded across the Fe 2p - 3d absorption threshold to obtain Fe specific spectral…
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…
