From: Photoemission study of the electronic structure and charge density waves of Na2Ti2Sb2O
The electronic structure of Na2Ti2Sb2O at 15 K.
(a) and (b), Photoemission intensity map at EF integrated over a window [EF - 10 meV, EF + 10 meV], data were measured with 100 eV photons energy. (c), The Fermi surface topology extract from (a) and (b). (d), The theoretic predicted Fermi surface of Na2Ti2Sb2O. (e1–e2), The experiment and theoretic23 valence band structure along Γ-M direction. (f1–f2), The experiment and theoretic23 valence band structure along Γ-X direction. Data were measured with 100 eV photons energy in (e) and (f). (g1–g2), The photoemission intensity and its second derivative of the intensity plot with respect to energy along Γ-M direction. (h1–h2), The photoemission intensity and its second derivative of the intensity plot with respect to energy along Γ-X direction, data were measured with 114 eV photons energy.
