Exploring the influence of Ni doping thin films for supercapacitor application

“…This observation highlights the existence of metal-oxygen bonds, which confirms the formation of the perovskite structure that is typical of BiFeO 3. 30 Furthermore, the peak observed at 674 cm À1 indicates the vibration of oxygen atoms in a direction perpendicular to the (111) plane of the rhombohedral structure of BFO, providing additional evidence of the material's crystalline structure. 31 In addition, there are peaks observed at 866 cm À1 which indicate the bending vibrations of Bi 2 O 3 .…”

Enhanced Photocatalytic Water Splitting of SrTiO3 Perovskite through Cobalt Doping: Experimental and Theoretical DFT Understanding

“…Afterward, we performed the Rietveld refinement (described in the Supporting Information) on the X-ray diffraction data using the Full-Prof program to provide different structural parameters such as unit cell, symmetry, and atomic positions. The structural refinements were carried out with the cubic structure in the Pm 3̅ m symmetry for different concentrations of Co dopant in the Ti-site using an initial model of STO .…”

The effect of Sr substitution on the structural and physical properties of manganite perovskites Ca1−xSrxMnO3−δ (0 ≤ x ≤ 1)

“…Generally, the formation of a single phase, structural stability, and structural distortion of ABO 3 -type perovskite structure can be analyzed using the tolerance factor ( τ ). In this study, we calculated the tolerance factor of the studied Ca 1− x Sr x MnO 3− δ perovskite materials using the following expression: 54,55 In this expression, r Ca 2+ , r Sr 2+ , r Mn 4+ , and r O 2− are the ionic radii of calcium, strontium, manganese and oxygen, respectively, where, r Ca 2+ = 1.34 Å, r Sr 2+ = 1.44 Å, r Mn 4+ = 0.67 Å and r O 2− = 1.40 Å. 51 In general, the perovskite structure is stable for the tolerance factor from 0.75 to 1.02.…”
