Electronic structure of the alternating monolayer-trilayer phase of
La3Ni2O7
Signatures of superconductivity near 80 K were recently discovered in crystals of La-Ni-O with the stoichiometry of 3:2:7 under high pressures. Structural studies have shown conflicting results highlighting both the expected bilayer (2222) structure and an unexpected alternating monolayer-trilayer (1313) structure, both apparently showing superconductivity. Here, we perform angle-resolved photoemission …
