Figure 3
(a,b) Geometry 1 and 2 for the ARPES on de-twinned crystals, respectively. (c) Momentum cut corresponding to the Geometry 1 (2) as indicated by a red (blue) line. Photons of hν = 40.8 eV probe the BZ center near the Γ plane and the BZ corner near the Z plane, respectively. (d1,d2) ARPES images of de-twinned BaFe2(As0.7P0.3)2 at 12 K (T < Tc) by around X along k y and Y along k x , respectively. The peak positions from EDCs and MDCs of ARPES images are superimposed by red (xz) and blue (yz) markers, respectively. (d3) Differences between APRES images around X(||k y ) and Y(||k x ) at 12 K. Red and blue intensities represent δ bands of xz and yz orbitals, respectively. (e1–e3) Similar to (d1-d3) recorded at 30 K (T ∼ Tc). (f1–f3) Similar to (d1–d3) recorded at 150 K (T ≫ Tc).
