abstract = {The optical conductivity (σ1) of SrTiO3 for various
vacancies has been systematically studied using a
combination of ultraviolet-vacuum ultraviolet reflectivity
and spectroscopic ellipsometry. For cation (Ti) vacancies,
σ1 shows large spectral weight transfer over a wide range
of energy from as high as 35 eV to as low as 0.5 eV and
the presence of mid-gap states, suggesting that strong
correlations play an important role. Meanwhile, for anion
(O) vacancies, σ1 shows changes from 7.4 eV up to
35 eV.},
