Preparation of SrTiO3 buffer layers on BaxSr1−xTiO3 seed layers buffered Ni tapes by chemical solution deposition

Abstract

SrTiO3 (STO) buffer layers were prepared via chemical solution deposition (CSD) on different BaxSr1−xTiO3 (BST, x=0, 0.3, 0.5) seed layers buffered Ni(200) tapes. It was found that (200) texture of the STO buffer layer was the best when the seed layer was Ba0.3Sr0.7TiO3. Additionally, the annealing temperature effects on the textures of STO(200) buffer layers were also studied, it was found that the STO buffer layers showed the best (200) texture when the annealing temperature was 900 °C.
