What makes the Tc of FeSe/SrTiO3 so high? |
(a) Reproduction of data from Ref. [ 9 ]. What is shown is the second energy derivative of the ARPES intensity as a function of momentum around the M point of the Brillouin zone. (The M point is the equivalence of the X and Y points in Fig. 1 .) (b) A reproduction of the angle-integrated photoemission data of H2 molecular gas from Ref. [ 18 ]. |
