2021年5月1日 · X-ray photoelectron spectroscopy (XPS, Thermo Fisher Scientific, ESCALAB250Xi) was employed to analyze the chemical binding states of the CuI sample with 200 nm thickness. During spectra acquisition, the base pressure was 2 × 10 −10 mbar achieved by turbo molecular pump.

2023年10月1日 · The I 3d XPS profiles (Fig. 3 g) in CuI display two strong peaks at 619.50 eV and 631.00 eV, which can be indexed to I 3d 5/2 and I 3d 3/2. The binding energy of elements C, Ni, Fe, Cu and I in NFCG-2 is shift to a certain extent from NiFe PBA, CuI and GD, which reveals the existence of strong electron migration between NiFe PBA, CuI and GD.

Cu (2p3/2) 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.

2022年4月15日 · The conjecture was later confirmed by X-ray photoelectron spectroscopy (XPS) and X-ray auger electron spectroscopy (AES) measurements. It was found that copper is further reduced and iodine is further oxidized after laser irradiation, …

XPS Spectra Copper (Cu) 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.

中文翻译： XPS的CuI 提出了高纯度CuI的X射线光发射测量。在该实验室中对铜化合物进行XPS研究的动机是，需要鉴定化学刻蚀的高温超导体表面上的物种[参见RP Vasquez，MC Foote和BD Hunt，J. Appl。

1993年4月1日 · X-ray photoemission measurements of high purity CuI are presented. XPS studies of Cu compounds in this laboratory have been motivated by the need to identify sp

Recently, a study of the surface chemistry of the flotation separation of chalcocite (Cu2S) from heazelwoodite (Ni3S2) employed a fitting procedure and calculation that quantifies the amount of Cu (II) species present on the surface of Cu (I) sulfide[1] as first developed by Jasieniak and Gerson (2004) and now described in reference [2].

2019年10月24日 · These spectroscopic studies together with the shake-up peak in XPS confirm the presence of Cu(II) in 2. The coupling mode between two hydroxo-bridged Cu(II) ions in 2 was subsequently explored by...

Here, we propose the construction of bicontinuous structure of Cu2O/Cu electrocatalyst, which consists of ultra‐small Cu2O nanodomains, Cu nanodomains and large amounts of grain boundaries between...
