Web18 Feb 2024 · The perovskite La 1−x Ca x NiO 3 precursor thin films were synthesized by a pulsed laser deposition (PLD) technique and reduced to an infinite-layer phase using the soft-chemistry topotactic reduction method. The x-ray diffraction (XRD) θ-2θ patterns of the as-grown La 1−x Ca x NiO 3 thin films can be found in fig. S1. The prominent thickness … Web3 May 2016 · When the precursor film was reacted at 240 °C, [001]-oriented NdNiO x H y (x ∼ 2.3, y ∼ 0.7) with a defect-fluorite structure was grown on a thin interfacial layer of infinite-layer NdNiO 2. At the elevated reaction temperature of 400 °C, we observed the growth of a [110]-oriented defect-fluorite phase, although it seemed more poorly lattice-matched to …
