LaCoO3 thin films deposited on SrTiO3 (100) single crystal substrates using the Pulsed Laser Deposition method were found to be grown highly c-axis oriented. Structural studies reveal that ...

2021年4月11日 · XRD spectra obtained were critically analysed using Rietveld analysis method to confirm the purity of the synthesized phase. XRD spectrum of STO-GC revealed 100% pure crystalline phase of cubic STO as shown in Fig. 4a. For STO-IG, the results revealed the presence of TiO 2 rutile phase along with cubic phase of STO as given in Fig. 4b.

Fig. 2 (a) shows the phase compositions of STO and NSTO targets verified by XRD, both of which present only one titanate phase with the typical perovskite structure. However, compared to STO...

2015年3月6日 · In this paper, we investigate the surface properties of poly-crystalline SrTiO 3 (STO) and pursue an atomically smooth surface for poly-crystalline TMO thin film growth. STO was chosen as it is...

2016年6月19日 · 以烧结的Fe304为靶材，在STO（100）基底上制备了FeO（100）薄膜。 XRD和AFM显示薄膜为纯相外延单晶薄膜、表面较平整。 对薄膜的磁电阻进行测量，薄膜为负磁电阻，且在Verwey转变温度（约120K）时磁电阻最大。

1999年9月1日 · LaNiO 3 (LNO) thin films were spin-coated onto the SrTiO 3 (100) (STO) substrates by the chemical solution method. X-ray diffraction (XRD) θ-2θ scans and X-ray β scans were used to determine the crystallinity and in-plane alignment behavior of the films.

In this present research, BFO has been epitaxially grown on SrTiO3 (STO) substrates having various crystal orientations; (100), (110), and (111). We found that the lattice matching hold a...

钛酸锶(SrTiO3，以下简称STO)是一种重要的电子材料，是典型的钙钛矿结构氧化物，具有丰富的物理现象。在105K，单晶STO发生立方(Pm3m)-四方(I4/mcm)结构相变，由TiO6八面体沿长轴旋转引起，相邻的两个TiO6八面体旋转方向相反，晶体单胞对称性降低且体积变大。

2007年2月7日 · 通过氧等离子体辅助分子束外延在 SrTiO3 (STO)(100) 上生长氧化亚铜 (Cu2O)。 使用X射线衍射（XRD）、X射线光电子能谱（XPS）、原子力显微镜（AFM）和横截面透射电子显微镜（TEM）分析生长层的微观结构和Cu价态以及电子衍射。

2019年11月14日 · To check the epitaxial nature of the BZT/BCT films on SRO buffered STO (100) substrate, high-resolution XRD measurement of the heterostructure was performed and shown in figure below.
