Superconductivity and electronic structures of nickelate thin film superstructures

Ruddlesden–Popper nickelates have emerged as a crucial platform for exploring the mechanisms of high-temperature superconductivity1–7. However, the Fermi surface topology required for superconductivity remains unknown. Here, beyond the superconducting pure bilayer (2222) phase, we report the thin film growth and ambient-pressure superconductivity of monolayer–bilayer (1212) and bilayer–trilayer (2323) superstructures, together with the absence o…

Nickelate Thin Films: Superconductivity and Structures

In recent years, the quest for understanding and harnessing high-temperature superconductivity has taken a thrilling turn with the emergence of Ruddlesden–Popper nickelates as a pivotal platform. These layered nickel oxide compounds have captivated researchers, offering new avenues to probe the complex interplay of electronic correlations and lattice structures that give rise to superconductivity at relatively high temperatures. Despite impressi…
