Structural quality of LuFeO 3 epitaxial layers grown by pulsed-laser deposition on sapphire substrates with and without platinum Pt interlayers has been investigated by in situ high-resolution X-ray diffraction (reciprocal-space mapping).

Dec 18, 2024 · Bulk LNO, bulk LFO, and the (LNO) 3 /(LFO) 1 SL configurations were represented using the 2 by 2 by 4 supercells and strained to the STO(001) and LSAT(001) substrate. In all cases, the off-interface lattice parameters were adjusted to minimize the total energies of the corresponding systems.

Feb 14, 2025 · In this study, we propose a lattice modulation strategy that incorporates cobalt substitution at the iron sites of LFO, resulting in the novel compound Li 5.5 Fe 0.5 Co 0.5 O 4 (LFCO), which enhances both the anionic redox activity and the air stability of the material.

Mar 8, 2025 · In this study, pure Lanthanum ferrite LaFeO 3 (LFO) nanoparticles were fabricated using the sol–gel auto-combustion method. Five samples of LFO/MWCNTs nanocomposites with (x = 0, 5, 10, 15, and 20 wt.%) were prepared via ultrasonication assisted procedure.

Feb 28, 2025 · However, the oxygen evolution mechanism in LFO remains unclear, limiting its application as an ideal prelithiation agent. Herein, we systematically track the full lifecycle oxygen footprint in LFO lattice, electrolyte and solid electrolyte interface (SEI).

Mar 5, 2025 · The substitution of Bi for La in the LFO lattice leads to charge redistribution. In a pure LFO lattice, a La 3+ ion is generated by transferring 2.1 electrons from a La atom to its neighboring O atoms.

Dec 15, 2022 · XRD patterns of LFO and LNFTO were analyzed by Rietveld method using MAUD program to confirm crystallographic phase purity, determination of lattice parameters, and proper substitution of co-doped cations and to find the presence of impurity, if any.

In this study, we propose a lattice modulation strategy that incorporates cobalt substitution at the iron sites of LFO, resulting in the novel compound Li 5.5 Fe 0.5 Co 0.5 O 4 (LFCO), which enhances both the anionic redox activity and the air stability of the material.

Jan 4, 2011 · Through x-ray diffraction and Raman spectroscopy analysis we find LFO films grown on isostructural MgAl 2 O 4 (MAO) are closer to bulk single crystal behavior, whereas the films remain coherently strained on lattice matched MgO substrate.
