“…This calculation gives results that are similar to those presented in Ref. [18], both in the general shape of the occupied p-states and in the relative weights of the Ti and O states. It also meets previous experimental results [19].…”

“…Surprisingly, the relative O character is strongly suppressed, including the O 2s states, in contrast to other studies at similar energies (which do not attempt to optimize agreement between experiment and theory). 26,27 However, it is clear from Fig. 2(b) that the shape of the O 2s PDOS is incompatible with the data.…”

We report hard x-ray photoemission spectroscopy measurements of the electronic structure of the prototypical correlated oxide SrxCa1−xVO3. By comparing spectra recorded at different excitation energies, we show that 2.2 keV photoelectrons contain a substantial surface component, whereas 4.2 keV photoelectrons originate essentially from the bulk of the sample. Bulk sensitive measurements of the O 2p valence band are found to be in good agreement with ab initio calculations of the electronic structure with some modest adjustments to the orbital-dependent photoionization cross-sections. The evolution of the O 2p electronic structure as a function of the Sr content is dominated by A-site hybridization. Near the Fermi level, the correlated V 3d Hubbard bands are found to evolve in both binding energy and spectral weight as a function of distance from the vacuum interface, revealing higher correlation at the surface than in the bulk.
