Description
The electronic structure of doped Mott-insulator La1-xSr xTiO3 has been studied by resonant soft-X-ray emission spectroscopy (SXES). The Raman scattering of the eg- and t2g-resonant SXES spectra indicates features due to the d-d transitions corresponding to the crystal field splitting (10Dq) and half on-site Coulomb energy (U dd/2), respectively. The U dd does not change much around two metal-insulator transitions at x = 0.05 and 0.95 in La1-xSr xTiO3, while the 10Dq increases as a function of x. These results are in good agreement with the prediction of dynamical mean field theory calculation
