Abstract
We have studied the satellite structure appearing in the Ti 1s and Ti 2p core-photoelectron spectra of the transition-metal oxide SrTiO3 by high energy resonant photoelectron spectroscopy (HERPES). We demonstrate experimentally that the two satellites observed in both spectra are due to ligand to metal shake-up charge transfer. This assignment is based on the energies of the different resonant K-L2L3 Auger decays that follow Ti 1s photo-excitation. The satellites are attributed to ligand 2p t2g → metal 3d t2g and ligand 2p eg → metal 3d eg monopole transitions that are consistent with energy assignments and intensities based on molecular orbital theory. Our data are also shown to be consistent with recent theoretical calculations.Citation
