2022年11月9日 · Bismuth ferrite (BiFeO 3 or BFO), is an extremely promising multiferroic material having broad range of applications. In the present study, we investigated the optimization of annealing temperature for the preparation of pure phase bismuth ferrite using quantitative Rietveld analysis of XRD patterns.

We report the domain structure, ferroelectric, piezoelectric, and conductive properties of bismuth ferrite (BFO, short for BiFeO3) nanowires characterized by scanning probe microscopy (SPM). The...

2024年12月1日 · The crystal structure of (1-x)BiFeO 3-x(Na 0.8 Bi 0.1)(Nb 0.75 Ta 0.15 Ti 0.1)O 3 ceramics is investigated using X-ray diffraction (XRD), as shown in Fig. 2 a.

2017年9月1日 · The surface morphology of the BFO films were investigated by atomic force microscopy (AFM) in tapping mode and scanning electron microscopy (SEM). The orientation and crystallinity of the thin films were studied by high-resolution X-ray diffraction (XRD) with Cu K α radiation. High-resolution transmission electron microscopy (HRTEM) and energy ...

The sharp diffraction peaks of both constituent nanostructures of BFO and ZnO are observable in the XRD pattern of the prepared ZnO-BFO in three ratios of ZB21, ZB12, and ZB11, indicating the...

2019年2月28日 · XRD studies have confirmed that all BFO NPs show distorted rhombohedral crystals that match the R3c space group. We found evidence of local structural strain that develops with increasing...

2018年1月17日 · In addition, we demonstrate (1) why hexagonal notation rather than pseudocubic one is required for accurate BFO phase evaluation and (2) a new XRD method that shows how rhombohedral BFO can...

This paper presents the preparation of KBiFe2O5 thick film and its optical (bandgap), ferroelectric, and photovoltaic properties. The XRD of KBiFe2O5 film reveals orthorhombic crystal structure.

2016年12月1日 · The X-ray diffraction (XRD) and the high-solution XRD reciprocal space mapping (RSM) techniques were employed to analyze the structures of these BFO films, using the Rigaku SmartLab (9 kW)...

2021年3月1日 · The XRD scans show peak shift of CCMO with thickness from 0 u. c. to 24 u. c, implying the O-R-T phase transition in BFO is driven by the gradual strain relaxation of CCMO interface layer.
