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

 Static and ultrafast dynamics of defects of SrTiO3 in LaAlO3/SrTiO3 heterostructures [PDF]

Applied Physics Letters, 2011
A detailed defect energy level map was investigated for heterostructures of 26 unit cells of LaAlO3 on SrTiO3 prepared at a low oxygen partial pressure of 10−6 mbar. The origin is attributed to the presence of dominating oxygen defects in SrTiO3 substrate.
