(a-c) Experimental Bi 4f holograms of Pb-La(O, F)BiS2 at 150 K, 50 K, and 150 K hologram divided by 50 K hologram, respectively. (d-f) the same as (a-c), but for La(O, F)BiS2. (g, h) simulated hologram based on a tetragonal structure model18, monoclinic structure model6, and the tetragonal structure mode with a Bi atom position shift by 0.2 Å. Maximum and minimum intensity values are indicated. The scale bar is for the experimental holograms.
