a) XPS spectra for the NbNx films grown on AlN at 800, 1100, 1200, and 1210 °C. b) Ratio of the areas of N 1s and Nb 3p peaks in the XPS spectra. [...] The structural similarity between...

Niobium (Nb) is a transition metal known for its exceptional properties, making it important in various industrial and scientific applications. It is widely used in alloy production, especially in superalloys, where it enhances strength, corrosion resistance, and heat resistance.

In the case of Nb 3d core level line (Figure 7 (d)), signals from carbide and oxygen species are detected. In particular, the dominant NbC doublet is observed at the BE of 203.8 eV (3d 5=2 ) and...

The Nb 3d XPS pattern of NCM1 is shown in Fig. 3c. The peaks located at 206.2 eV and 209 eV represent the characteristics of Nb 3d 5/2 and Nb 3d 3/2 , respectively, indicating that the...

The International XPS Database provides - XPS survey spectra, XPS peak-fitted spectra, XPS valence band spectra, plasmon spectra, and six (6) tables of BEs.

2017年8月22日 · We present high-resolution XPS spectra of elemental vanadium, niobium and tantalum sputter-cleaned by Ar + ions. The energy scales are shown without applying any corrections, and the position of the Fermi level was verified to be at zero binding energy within better than 0.1 eV, as determined from the Fermi edge measurement.

Nb (3d5/2) Chemical State BEs from: “The XPS Library Spectra-Base” Charge Referencing Notes. (N*number) identifies the number of NIST BEs that were averaged to produce the BE in the middle column. The XPS Library uses Binding Energy Scale Calibration with Cu (3d5/2) BE = 932.62 eV and Au (4f7/2) BE = 83.98 eV. BE (eV) Uncertainty Range: +/- 0.2 eV.

2018年5月1日 · The analysis of XPS results concerning core levels of Nb 3d, O 1s, C 1s, F 1s, and N 1s is presented in Table 3. A higher percentage of nitrogen of about 2% exists on the surfaces of doped samples, resulting from the diffused nitrogen during …

2011年2月1日 · Fe2p, Fe3p, and Fe3s X-ray photoelectron spectra (XPS) are measured with high resolution in single-crystal multiferroics BiFeO 3 and PbFe 1/2 Nb 1/2 O 3, as well as in reference samples Fe 2 O 3, FeSO 4 ·7H 2 O, FeC 2 O 4 ·2H 2 O. The spectra are assigned based on an isolated-ion approximation calculation.

2019年4月15日 · Effect of samarium in Nb5+ and Ta 5+ structures was studied using XPS method. Binding energy differences revealed characterize average Nb O and Ta O bonding. XPS confirmed Sm3+ and Sm 2+ valence states in ratio 21/1 (SNO) and 24/0.3 (STO).
