    • The invention relates to a nanostructured BaTiO3 film, plate or array that has from 1,000 to 10,000 times the storage capacity of conventional capacitors. The barium titanates are of the formula BaaTibOc wherein a and b are independently between 0.75 and 1.25 and c is 2.5 to about 5.0. The barium titanates may further be doped with a material, “M”, selected from Au, is Au, Cu, Ni3Al, Ru or InSn. The resulting titanate may be represented by the formula MdBaaTibOc wherein d is about 0.01 to 0.25, a is about 0.75 to about 1.25, b is about 0.75 to about 1.25 and c is about 2.5 to about 5.0. X-ray diffraction results illustrate that the crystal structure of the thin films changed from predominantly cubic to tetragonal phase and crystallite size increased with increasing concentration of “M”.
    • 本发明涉及一种纳米结构的BaTiO3膜,板或阵列,其具有常规电容器的存储容量的1,000至10,000倍。 钛酸钡具有式BaaTibOc,其中a和b独立地在0.75和1.25之间,c是2.5至约5.0。 钛酸钡还可以掺杂有选自Au的“M”,为Au,Cu,Ni3Al,Ru或InSn。 所得钛酸酯可以由式MdBaaTibOc表示,其中d为约0.01至0.25,a为约0.75至约1.25,b为约0.75至约1.25,c为约2.5至约5.0。 X射线衍射结果表明,薄膜的晶体结构从主要立方向变为四方晶相,微晶尺寸随“M”浓度的增加而增加。
