Tantalum electron configuration, X-ray photoelectron spectra, and other elemental information – part of the XPS Reference Table of Elements.

Data Collection Settings for Tantalum (Ta) Conductivity: Tantalum readily develops a native oxide that is sensitive to Flood Gun – Differential Charging Possible – float sample recommended; Primary Peak (XPS Signal) used to measure Chemical State Spectra: Ta (4f 7 /2) at 21.8 eV

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, such...

X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra.

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. Peak-fits are guides for practical, real-world applications.

2012年10月1日 · In our study, the chemical states of Ta and MgO x at the interface of the NiFe/MgO x /Ta films, which were prepared at the different technological conditions, were analyzed by X-ray photoelectron spectroscopy (XPS). The results show that the chemical states of the atoms are related to the different technological conditions, and influence the ...

1998年8月14日 · Two kinds of tantalum oxide films have been studied by XPS: dry and electrogenerated anodic oxides. XPS spectra of Ta4f and O1s have been used to determine the chemical composition of the different films. Ta 2 O 5 is the main constituent of thick films (15 nm≤ dox ≤60 nm), although the concomitant presence of sub-oxides (mainly TaO) is observed.

氧化钽被氩离子束还原，形成一系列氧化态化合物，如 Ta 2 O 5 、Ta 3 O 7 、Ta 4 O 9 等。 尽可能使用较低的离子束能量进行深度剖析或者用团簇模式进行表面清洁（如果可以的话）。 钽是过渡金属，熔点高，于1802年由 A.Ekberg 从铌中分离而得。 纯钽可以被拉成细线，用作蒸发金属的细丝。 由于其熔点高、有延展性和耐腐蚀，通常会掺入到各种金属合金中，用于化学加工设备、电容器和飞机部件。 已知金属合金碳化钽石墨是最硬的金属之一，熔点为3738℃。 钽金属无刺激 …

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...
