Abstract

The defect structure of perovskite Ba0.3Sr0.7TiO3 (BSTO) film grown on (001) LaAlO3 was studied. Conventional and high-resolution transmission electron microscopy was used for analysis. The epitaxial film was grown using pulsed laser deposition (PLD). The initial BSTO layer experienced nucleation and coalescence of 3D islands as well as misfit strain relaxation. A discussion about generation, dissociation and evaluation of the threading dislocations (TD) was also made.
