Abstract

Pt-coated silicon substrates with strong (111) Pt texture were annealed in an oxidizing atmosphere at various temperatures. Dependence of the microstructure and morphology on oxygen partial pressure for SBLN films prepared by pulsed laser deposition were investigated by using X-ray diffraction and atomic force microscopy. The grain size and growth habits of SBLN films were influenced by oxygen partial pressure. As oxygen pressure increases at 10 Pa, nucleation and grains growth of the SBLN films were mainly influenced by the Pt grains of substrate. (100) and (310) texture growth of the SBLN film was revealed, and the film had good ε(f) properties.
