金纳米粒子在钛酸钡薄膜中的相互作用
Interaction of Gold Nanoparticles in Barium Titanate Thin Films
摘要:
研究了一种控制氧化物薄膜材料晶粒尺寸的新方法。当沉积在预沉积金的(111)取向的硬晶SrTiO 3衬底上时,过氧化氢BaTiO 3显示出有趣的晶粒结构。固体氧化物薄膜外延生长图案化的种子层,并显示相对于直接沉积在SrTiO 3上的薄膜的晶粒尺寸的变化。
英文摘要:
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.
