Figure 2. Constant energy surfaces and high-symmetry cuts of the parent and Rh-doped Sr₂IrO₄.

(a,b) The constant energy surfaces of the parent (a) and x=15% Rh-substituted (b) Sr₂IrO₄. The numbers are binding energies relative to E_F. The solid white/dashed blue lines are the folded/original BZs. (c) ARPES energy-momentum intensity plots along Γ'−(π, 0)−Γ' (yellow lines in panels (a,b)). The dashed green and white lines through the data guide the eye for the J_1/2 and J_3/2 bands, respectively.
