Crystal structure stability and electronic properties of the layered nickelate La4Ni3O10

“…10 In this Rapid Communication, we show that the orthorhombic Bmab phase of La 4 Ni 3 O 10 is unstable at lowtemperature and undergoes a structural phase transition to monoclinic P 2 1 /a using ab initio calculations. We find that the low-energy electronic structure of this monoclinic phase is in better agreement with previously published ARPES data, 11 suggesting that the structural phase transition is a necessary component to achieving a complete description of the physics in La 4 Ni 3 O 10 .…”

“…The study describes the similarities and differences between the low-energy electronic structure of layered cuprates and nickelates. Moreover, the experimental evolution of the Fermi surface as a function of temperature shows the appearance of a pseudogap between 120 and 150 K, which suggests a connection with the anomaly observed in the temperature-dependent resistivity ∼140 K. 10,11 This prior work did not consider the possibility of a structural transition, despite the established importance of lattice instabilities on both metallicity and superconductivity. 12-14 Indeed, Li et al 11,15 interpret their data by assuming that the layered nickelate La 4 Ni 3 O 10 maintains its Bmab symmetry over the entire temperature range analyzed.…”

“…[6][7][8] For example, trilayered perovskite R 4 Ni 3 O 10 compounds are members of a small family of oxides that exhibit metallic conductivity even at low temperatures. 9 Interesting, these compounds undergo a metal-to-metal transition between 140 K and 165 K. [9][10][11] Recently, Li et al 11 analyzed the Fermi surface of the trilayer nickelate La 4 Ni 3 O 10 using angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) band structure calculations. The study describes the similarities and differences between the low-energy electronic structure of layered cuprates and nickelates.…”

“…Also, the lack of band splitting in the monoclinic P 2 1 /a phase results in better agreement between the DFT band structure and the observed low temperature Fermi surface. 11 In Fig. 3d has 2 formula units, see Supplementary Interesting, the low-energy electronic band structure of the monoclinic-II P 2 1 /a (Fig.…”
