Compositional, structural and electrical characterization of barium titanate thin films prepared on fused silica and Si(111) by spray pyrolysis

Control of the nanostructure in percolative multiferroic composites on the dielectric loss and magnetism threshold

“…The lattice constant of the BTO phase is thus independent of the ferrite content as shown in Fig. [25][26][27][28] The Fe 2p region is composed of the peaks with respect to Fe 3+ and Fe 2+ ~ 720 eV, [27][28][29][30] as well as their satellite and surface state peaks. As can be seen, the O 1s region of the photoelectron spectrum is composed of the peak at ~ 531 eV which is assigned to the non-lattice oxygen, [25][26][27][28] and the peak at ~ 530 eV which is assigned to lattice oxygen.…”

Comment on “The Effect of Barium Substitution on the Ferroelectric Properties of Sr2Nb2O7 Ceramics,” J. Am. Ceram. Soc., 96 [4] 1163–70 (2013)

“…The ΔBE Sr = 396.5 eV found in Sr 2− x Ba x Nb 2 O 7 (0.1 ≤ x ≤ 0.5) solutions is evidently lower than the typical values observed in Sr‐containing oxide crystals . The value of ΔBE Ba = −249.9 eV is also below the range of ΔBE Ba = −(249.2–249.5) eV common in oxides . As to the niobium level, the value is calculated as ΔBE Nb = 322.7 eV, and that is also below the range of ΔBE Nb = 322.8–323.5 eV observed in Nb 5+ oxides .…”

Characteristics and mechanisms of aerosol deposition-based barium titanate by sulfur hexafluoride inductively coupled plasma etching

“…2(c)-(1). Because the BTO film consists of two components (BaO and TiO 2 ) in a BTO solid solution and C-O bonds due to surface contamination, the sub-peaks are mainly ascribed to Ba-(O 1s) (780 eV), Ti-(O 1s) 2 (529 eV), and C-(O 1s) (532.3 eV) bonds [8,[12][13]. The significant shoulder is attributed to O vacancies and surface species, such as H 2 O and CO 2 , adsorbed from the air during the AD process.…”
