(a and b) depict the ARPES intensity plots taken at 31 eV photon energy along the Γ-K direction taken ~10 and 27 hrs. after the sample cleaving. (c and d) Show the same images along Γ-M direction collected at different time intervals from the cleaving. (e–h) Show MDC spectra extracted from the images (a–d). The dispersion relation between E and k estimated from the MDC plots are fitted to the calculated values obtained from the model Hamiltonian28 along the Γ-K (i) and the Γ-M (j) directions.
