Optical response of SrTiO3 thin films grown via a sol-gel-hydrothermal method

Chimica Techno Acta, 2023
The polycrystalline SrTiO3 thin films were prepared by the sol-gel-hydrothermal method on glass substrates. The synthesis pathway was initiated by preparing a clear TiO2 solution using the sol-gel method. This clear solution was then deposited on a glass

Robust Ti4+ states in SrTiO3 layers of La0.6Sr0.4MnO3∕SrTiO3∕La0.6Sr0.4MnO3 junctions [PDF]

Applied Physics Letters, 2006
We have investigated the interfacial electronic structure of La0.6Sr0.4MnO3 (LSMO)∕SrTiO3 (STO)/LSMO heterojunctions utilizing the elemental selectivity of photoemission spectroscopy. The Ti 2p core-level spectra clearly show Ti4+ states and do not exhibit any indication of Ti3+ states in TiO2 layers irrespective of a different kind of adjacent atomic ...
