Fig. 4: DFT calculation on La4Ni3O10.
From: Absence of superconductivity and density-wave transition in ambient-pressure tetragonal La4Ni3O10
a The band structure of ambient pressure P21/a phase. b The band structure of high pressure (40 GPa) I4/mmm phase. c The band structure of ambient pressure I4/mmm phase. d The Fermi surface of ambient pressure P21/a phase. The Brillouin zone (dashed lines) is folded due to tilted octahedrons. e The Fermi surface of high pressure (40 GPa) I4/mmm phase. f The Fermi surface of ambient pressure I4/mmm phase. Notice that there are two additional Fermi pockets around Brillouin zone center and corner.
