a Schematic drawing of the lattice structure of BaFe2(As0.7P0.3)2. The black solid line illustrates the position of a possible cleavage plane. b Schematic drawing of the cleavage surface and potassium deposition. c Fermi surface mapping taken in the pristine sample (D0). kx and ky are the momenta of electrons along x and y directions. Panel d is the same as c but taken in the doped sample (D3) after three times potassium deposition.
