TL;DR
This study explores how gold nanoparticles influence the grain structure of barium titanate thin films, revealing that gold seed layers can modify grain size and epitaxial growth in oxide films.
Contribution
It introduces a novel method of controlling grain size in oxide thin films using gold nanoparticle seed layers, advancing thin film fabrication techniques.
Findings
Gold seed layers alter grain size in BaTiO3 films.
Epitaxial growth is achieved on gold-patterned substrates.
Grain structures vary with different seed layer configurations.
Abstract
A novel approach to control the grain size of oxide thin film materials has been investigated. Perovskite BaTiO3 shows interesting grain structures when deposited on gold predeposited, (111)-oriented, singlecrystal SrTiO3 substrates. Solid oxide films grow epitaxially on patterned seed layers and show variations in grain size relative to the films deposited on SrTiO3 directly.
