Niobium Spectra – NbN – The International XPS Database 1
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.
Angle-resolved XPS studies of oxides at NbN, NbC, and Nb surfaces
NbN, NbC and Nb are known to be chemically inert with passivating oxides only solvable in HF acid. Despite Nb 2 O 5 as outermost oxide layer, the oxides of Nb compounds show large differences in thickness and in electronic properties. To quantify the differences, angle-resolved XPS (ARXPS) measurements have been performed.
Electron spectroscopy study in the NbN growth for NbN/AlN …
2007年7月1日 · In this paper we report (i) the sputtering parameters found during the growth of the NbN/AlN interface at room temperature; (ii) the X-ray photoelectron spectroscopy (XPS) results which give the electronic structures of the Niobium nitride and information on the stoichiometry; and (iii) the X-ray diffraction (XRD) data, to yield information on ...
XPS study of NbN and (NbTi)N superconducting coatings
1996年10月30日 · Therefore, an X-ray photoelectron spectroscopy (XPS) study of the extreme surface ( < 10 nm) of NbN and (NbTi)N thin films was undertaken to improve the comprehension of the nature and thickness of the surface oxides.
氮化铌表面氧化物的XPS研究 - 物理学报
本文用x射线光电子能谱(xps)对室温下自然氧化和射频氧化的氮化铌薄膜表面进行了成分分析。 指出:与在类似条件下纯铌膜的氧化不同,NbN膜的表面氧化物中不存在NbO和NbO2,而是以Nb2O3作为从NbN到Nb2O5-y的过渡相。

XPS STUDY OF THE OXIDES ON THE SURFACE OF NbN THIN FILM …
The composition of the oxides formed at room temperature in the atmosphere or by rf oxidation on the surfaces of NbN thin films were characterized by means of X-ray photoelectron spectroscopy. The experimental Nb3d spectra show that the interfacial phase formed between NbN substrate and the niobium pentoxide is different from the case of pure ...
Angle resolved XPS studies of oxides at Nb-, NbN-, NbC- and Nb
This first identification of the oxinitrides of the metallic suboxides and of the reduced serration of NbN (NbC) explains the improved oxide quality and quality of tunnel junctions and rf cavities as compared to defective Nb single cristals.
Angle resolved XPS studies of oxides at Nb-, NbN-, NbC- and Nb …
The surfaces of NbN(100) and NbN(111) single‐crystal films were analyzed as a function of annealing temperature in ultrahigh vacuum by low‐energy electron diffraction and x‐ray photoelectron …
