Extended Data Fig. 2: Additional structural analysis data.
From: Bulk superconductivity near 40 K in hole-doped SmNiO2 at ambient pressure
STEM-HAADF images show several areas of the representative Sm0.79Eu0.12Ca0.04Sr0.05NiO2 thin film. The infinite-layer film is virtually free of RP-type structural defects.
