Fig. 4: Band structures and Fermi surfaces of the two-obital models for La3Ni2O7 thin films.
From: Electronic structures and multi-orbital models of La3Ni2O7 thin films at ambient pressure
a and c correspond to the double-stacked two-orbital model for the One-UC slab, while b and d correspond to the single-stacked two-orbital model for the Half-UC slab. The color bar indicates the orbital weights, with red and blue represent \({d}_{{x}^{2}-{y}^{2}}\) and \({d}_{{z}^{2}}\), respectively. In a and b, the gray lines represent the DFT-calculated band structures with Ueff = 0 eV. The EF is set to 0 eV. Here, Ueff denotes the effective Hubbard parameter, and UC represents the unit cell.
