“…Similar satellites have been reported for various 3d transition metal oxides, including Ti oxides, and interpreted as charge transfer (CT) satellites [18,19]. Our cluster calculations well reproduce these 13 eV satellites due to CT excitations both for the λ and β phases as shown in Fig.…”

We have conducted hard x-ray photoelectron spectroscopy investigations of the electronic structure changes and electron correlation phenomena which take place upon the photoinduced reversible phase transition between β-and λ-T i 3 O. From valence band spectra of β-and λ-T i 3 O 5 , we have identified the bipolaron caused by the σ -type bonding of d xy orbitals in β-T i 3 O 5 and the π stacking between the d xy orbitals between different Ti sites in λ-T i 3 O 5 , previously predicted by ab initio calculations. This indicates that the single electron band picture is valid for the description of photoinduced phase transitions. On the other hand, the Ti 2p and Ti 1s core level spectra exhibit nonlocal screening satellite features, which are typical spectroscopic signs of strong electron correlation in the coherent Ti t 2g states. The most striking result we obtain is that correlation in the valence band also manifests to reduce the plasmon energy, which results in an enhancement of the valence electron mass by a factor of 2.7.

“…A high binding energy shake up satellite is observed at 471.5 eV. Various satellites of Ti 2p core level observed in TiO 2 and SrTiO 3 were explained in detail by Kim and Winograd [50]. According to them TiO 2 exhibits two satellites for Ti 2p 3/2 core level at 13.0 eV and 25.4 eV binding energies from the main peak.…”

“…The satellite we observed is at 13.3 eV higher in binding energy (471.5 eV) from the main peak (458.2 eV). This satellite can be attributed to a shakeup satellite of 2pe g → 3de g type monopole charge transfer [50]. Such satellite formation is observed only in Ti compounds with Ti 4+ valence state.…”

“…Kim and Winograd [7] interpreted similar data in terms of optical absorption spectra, and they assigned the observed satellites to monopole O 2p e g → Ti 3d e g , O 2p a 1g → Ti 4s a 1g , and O 2s e g → Ti 3d e g transitions in order of increasing energy. These authors concluded that the first shake-up satellite occurring on the high binding-energy side of a transition-metal compound must be due to ligand 2p e g → metal 3d…”

Loss for photoemission versus gain for Auger: Direct experimental evidence of crystal-field splitting and charge transfer in photoelectron spectroscopy

We find a new 5 eV satellite in the Ti 1s photoelectron spectrum of the transition-metal oxide SrTiO 3 . This satellite appears in addition to the well-studied 13 eV structure that is typically associated with the Ti 2p core line. We give direct experimental evidence that the presence of two satellites is due to the crystal-field splitting of the metal 3d orbitals. They originate from ligand 2p t 2g → metal 3d t 2g and ligand 2p e g → metal 3d e g monopole charge-transfer excitations within the sudden approximation of quantum mechanics. This assignment is made by the energetics of the resonant and high-energy threshold behaviors of the Ti K-L 2 L 3 Auger decay that follows Ti 1s photo-ionization.
