The TaN bare substrate (red line) XPS spectrum shows peaks at binding energies around 230.4 eV and 242.5 eV, which are distinctive of the 4d 5/2 and 4d 3/2 states of partially oxidized TaN,...

Novel tantalum (Ta) and chitosan (CS)-doped CuO nanorods (NRs) were synthesized using a single step co-precipitation route. Different concentrations (2 and 4%) of Ta were used in fixed amounts...

Ta (4f7/2) 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 (2p3/2) BE = 932.62 eV and Au (4f7/2) BE = 83.98 eV. BE (eV) Uncertainty Range: +/- 0.2 eV.

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).

XPS Spectra Tantalum (Ta) Compounds The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE.

Ta4f region has well separated spin-orbit components (Δmetal=1.92eV). Loss feature for Ta metal appears at ~33eV and ~38eV for Ta 2 O 5. Peaks in the Ta4f region have an asymmetric peak shape for tantalum metal. Tantalum compounds, such as the oxide, have symmetric Ta4f peaks.

43 High-resolution XPS of Ta 4f in TaNOC-2 and TaNOC-3 display similar species that contain Ta-O and Ta-N (Supporting Information: Figures S2A and S3A). These two species are also verified...

XPS 光谱解读. Ta4f 区域具有明显的自旋轨道分裂峰 (Δ 金属 =1.92 eV)。 钽金属在约33 eV处出现能量损失特征峰，Ta 2 O 5 在约38 eV处出现能量损失特征峰。 钽金属的 Ta4f 区域峰形不对称。 钽化合物（如氧化物）的 Ta4f 峰形对称。

2017年1月15日 · The films were characterized by XRD, GIXRD, HRSEM, AFM, XPS and nanoindentation. It was found that the nature of the substrate has a strong influence on the Ta phase formed. Formation of α-Ta phase was obtained on SS316LVM, but the β-Ta phase was formed on Ti and on TaN substrates.
