Extended Data Table 1 Pulsed-laser deposition growth parameters optimized for perovskite Nd1–xSrxNiO3 thin films on LSAT

From: Linear-in-temperature resistivity for optimally superconducting (Nd,Sr)NiO2

  1. The optimized infinite-layer films were obtained across x by reducing the perovskite films at 240–260 °C for roughly 2.5–4 h (see Methods). We note that under the same reduction conditions, complete reduction could not be achieved for x < 0.05 on LSAT, and thus we limit our study to x = 0.05–0.325 (see Supplementary Information). For growth on SrTiO3, the substrate was pre-annealed at 900 °C for 30 min at oxygen partial pressure \({P}_{{O}_{2}}=5\times {10}^{\mbox{--}6}\) Torr.
