XRD pattern of the BFO/BTO multilayered structure (Fig. 2) reveals that all the observed peaks correspond to either BFO or BTO phases only. Absence of any extra XRD peak in all prepared...

In this paper, multiferroic binary compounds BaTiO3 (BTO) and YFeO3 (YFO) were synthesized by the solid-state reaction method with varying concentration of x from 0 to 1.0 in the step size of...

2020年1月1日 · BaTiO 3 thin films (60 nm-thick) grown on SrTiO 3 /Si templates have been characterized for their structural and electrical properties. The epitaxy of the BaTiO 3 film on silicon was confirmed by X-ray diffraction with good crystallinity. The temperature-dependent structural properties were checked by infrared spectroscopy in absorption mode.

可以把薄膜溶解在盐酸里，然后分析溶解掉的溶液中Ba和Ti的比例，比如用ICP-AES。 XRD看不出来元素比例的。 或者把薄膜放在SEM里，看EDS的数据。 祝科研顺利！ 可以把薄膜溶解在盐酸里，然后分析溶解掉的溶液中Ba和Ti的比例，比如用ICP-AES。 XRD看不出来元素比例的。 或者把薄膜放在SEM里，看EDS的数据。 祝科研顺利！ 单从关键物相上跟标准卡比对可不可以验证Ba和Ti的比例呢？ 可以把薄膜溶解在盐酸里，然后分析溶解掉的溶液中Ba和Ti的比例，比如用ICP …

2019年3月27日 · According to the XRD and Raman spectroscopy analyses, the BTO particles evolved from a cubic to a tetragonal structure at a calcination temperature of 800 °C. The cubic-to-tetragonal phase transformation of sol-gel derived BTO particles occurred at a critical crystallite size of about 30 nm and a particle size of about 100 nm.

2021年11月1日 · Bauer et al. (2018) investigated real-time in-situ XRD on Ba 0.5 Sr 0.5 TiO 3 (BSTO) structural changes and revealed crystalline phase transitions and strain evolution. The observed changes in out-of-plane and in-plane lattices were exposed to tetragonal distortion and residual strain with respect to temperature.

In this study, nano-BaTiO 3 (BTO) powders were obtained via the solvothermal method at different reaction times and were investigated using transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectroscopy. The results were compared with those obtained for a larger crystallite size BTO powder (BTO-m).

2023年10月1日 · In this study, we present structural and dielectric properties of doped and un-doped BaTiO 3 (BTO) thin films samples. BTO sample were produced by non-vacuum process specifically sol-gel spin coating technique. The doped samples involve Co, Gd, Mn, Sr, and Zr in the Ba-site of the BTO.

2022年5月30日 · We demonstrate the remote epitaxy of BaTiO 3 (BTO) on Ge using a graphene intermediate layer, which forms a prototype of highly heterogeneous epitaxial systems. The Ge surface orientation...
