To address this challenge, we develop an in-situ process via the deposition of metallic aluminum in ultra-high vacuum (UHV), and we demonstrate the process by reducing NdNiO3 thin films. By characterizing the NdNiO3-x thin films dynamically during the reduction process, we show that the Ni valence and NdNiO3-x lattice constant can be precisely controlled at each step of the Al deposition process, while maintaining the film’s epitaxy and surface morphology. We also apply this reduction method to Nd6Ni5O16 films to synthesize Nd6Ni5O12 films, a system for which superconductivity has been recently reported. The metal reduction method is straightforward and widely applicable for square-planar nickelate systems.
