X‐Ray diffraction (XRD) patterns and Scanning electron microscopy (SEM) images reveal that such BFM-PT thin films show single perovskite structure and smooth surface without detected second...

2020年5月22日 · BST is essentially a perovskite-based solid solution of barium titanate (BaTiO 3) and strontium titanate (SrTiO 3), where BaTiO 3 is in ferroelectric (polar) phase at room temperature and it transforms from ferroelectric phase to paraelectric phase with a sharp transition at the Curie temperature of 403 K [11].

Barium Strontium Titanate (BST) thin film has been prepared by using sol-gel method. The samples are prepared with 2 different deposition layers (1 layer and 4 layer) and...

2004年2月1日 · BST ferroelectric thin films have been prepared by MOD on the Pt/Ti/SiO 2 /Si substrate under different annealing temperatures and annealing time and examined for application to infrared sensor. The BST film should be deposited at a high spin coating rate such as 4000 rpm to avoid macro crack in the film.

2023年5月22日 · XRD results show that all BZT-BST ceramics form stable solid solutions, with peaks shifting towards right with increasing BST content indicating that interplanar spacing decreased. FESEM results show that the average grain size gradually increased from 152 nm (BZT) to 895 nm (0.8BZT-0.2BST).

X-ray diffraction (XRD) analysis indicated the formation of a highly crystalline perovskite cubic phase for film deposited at substrate temperature 1023 K. Another set of...

properties of PVDF/BST nanocomposites have been studied using X-ray diffraction. The XRD results showed that the BST nanopowder obtained by hydrothermal method with a perovskite structure and the α and γ- PVDF crystalline phases appeared at pure PVDF and nanocomposites samples. The crystallite size was calculated using Scherrer and Williamson-

2024年9月15日 · Morphological and phase analysis of the synthesized nanoparticles were conducted using scanning electron microscopy (SEM) and X-ray diffraction (XRD). XRD results affirmed the presence of BST and CuNW, while SEM micrographs revealed BST deposition on CuNW surfaces in the hybrid BST@CuNW nanoparticles.

Six-layer Ba0.6Sr0.4TiO3 (BST) films are prepared by an improved sol-gel method. The effects of various preheating methods on morphology and dielectric properties are studied. XRD results reveal that all BST films preferentially grow along the (110) direction and have cubic perovskite structures, and that preheating can obviously enhance ...

X-ray diffraction (XRD) was used to analyze the phase compositions and lattice characteristics of the films. The absence of peaks from TiO2 in the XRD spectra of...
