Improving the synthesis and properties of SBT thin films by using SBT seeds

Holistic RBS–PIXE data reanalysis of SBT thin film samples

“…As presented before in detail [1,2], seeded and unseeded SBT films were prepared by spin-coating organic solutions of the required cations on Si/SiO 2 /Ti/Pt substrates followed by heat treatment at adequate temperatures. Different cation proportions were selected so as to obtain nominal stoichiometric and non-stoichiometric (Bi-deficient) compositions.…”

“…For seeded films, seeds were previously deposited by spin-coating on the substrate. The details of the experimental procedures have been published elsewhere [1]. Table 1 identifies the samples used in the current work.…”

“…A previous study on the synthesis of seeded and unseeded SBT thin films by some of the authors [1] showed that increase of the film crystallinity and improvement of the thin film ferroelectric properties were a result of the use of SBT seeds. Details on the role of the seeds as an improver of the thin film properties were then investigated [2], and it was concluded that the films synthesized without SBT seeds show the formation of an interface of variable content and/or shape, while the use of the seeds contributes to a higher stability of the film and electrode constituents.…”
