Fig. 2: Fermi surface evolution with temperature for FTS44.
From: Correlation-driven electronic reconstruction in FeTe1−xSex
a Measured Fermi surfaces as temperature is varied between 18 K and 174 K. b Simultaneously measured constant energy contours at −60 meV showing no change as a function of temperature. Polarization is as marked in the left-most panel of (a) indicating an in-plane polarization along Γ-M with a finite out-of-plane component. The red squares mark the Brillouin zone of the 2-Fe unit cell.
