Figure 2

Superconducting gap observed on the hole FSs with various kz in BaFe2(As1-xPx)2 (x = 0.30, Tc = 30 K).

(a–c) Symmetrized EDCs at kF points in the Γ-X direction taken below Tc. Vertical bars indicate the gap energy. (d) Correspondence between the incident photon energy, kz and the three-dimensional hole FSs (blue curves). (e) Second derivative plots of the ARPES spectra around the Γ point. (f) Gaps estimated in panels a–c are plotted as a function of hν.
