(Color online) Structure of BaTiO3 with oxygen vacancy and Ti positions of calculation.
Experimental Ti-L2,3 ELNES of tetragonal BaTiO3 and theoretical Ti-L2,3 ELNES of cubic and tetragonal-BaTiO3.
(Color online) Theoretical Ti-L2,3 ELNES of the perfect BaTiO3 and the Ti near oxygen vacancy (a) without and (b) with extra electron.
(Color online) Linear combine spectra of Ti-L2,3 of BaTiO3 that include oxygen vacancy(:Vo). Broadening width of the black (thick) and red (thin) lines are 0.5 eV and 1.2 eV, respectively. (a) Ti next to oxygen vacancy is +4 (without extra electron), (b) Ti next to oxygen vacancy is +3 (with extra electron). Deep and light red and gray colors mean high and low concentrations, respectively.
