Polarization dependent photoemission data of Na2Ti2Sb2O at 15 K.
(a), Experimental setup for polarization-dependent ARPES.(b), The Brillouin zone of Na2Ti2Sb2O and locations of the momentum cuts. (c1–c3) and (d1–d3), The photoemission intensity and its second derivative of the intensity plot with respect to energy along Γ-M taken with C+, p and s polarized light, respectively. (e1–e3) and (f1–f3), The photoemission intensity and its second derivative of the intensity plot with respect to energy along Γ-X taken with C+, p and s polarized light, respectively, data were measured with 100 eV photons energy.
