2023年6月15日 · Block-Approach allows for accurate fitting of metal and oxide signals in Cu 2p. Peak-fitting parameters for improved fitting of Cu 2+ in quantitative XPS. The photoemission spectra of Cu 2 p are one of the most studied.

Cu 2p spectra for a sputter cleaned Cu metal surface (bottom), Cu 2 O standard (2nd from bottom, a small amount of Cu(II) was found in this sample), CuO standard (3rd from bottom) and Cu(OH) 2 standard (top) [4].

2017年5月12日 · Chemical state X-ray photoelectron spectroscopic analysis of copper species is challenging because of the complexity of the 2p spectra resulting from shake-up structures for Cu (II) species and overlapping binding energies for Cu metal and Cu (I) species.

2014年2月1日 · We obtain full simulated spectra by fitting results of Eq. (5) to experimental XPS spectra (Cu 2p for Cu, Cu 2 O and CuO materials) with the F(E) and K sc XPS functions as the only inputs.

The experimental Cu 2p XPS spec-trum, shown in Fig. 1, exhibits a 2p1/2–2p3/2 spin-orbit dou-blet, each component being composed of a main peak plus satellites. The experimental spectral widths are found to be slightly different for the main peaks of the Cu 2p1/2 ~1.8 eV! and Cu 2p3/2 ~1.6 eV! bands, which is a result of the atomic

The high-resolution XPS spectrum of Cu 2p (Figure 4 a) can be deconvoluted into Cu 2p 1/2 and Cu 2p 3/2 with three satellite peaks located at 962.3, 943.5, and 940.6 eV. ... View in...

The high resolution Cu 2p spectrum of the CuS was revealed the binding energies at 932.4 eV and 952.4 eV corresponding to the Cu 2p 3/2 and 2p 1/2 . The Cu 2p 3/2 spectrum of CuS...

Figure 2 shows the binding energies of the Cu 2p core levels. The spectrum shows the spin–orbit components Cu 2p 3 / 2 and Cu 2p 1 / 2 , at about 931 and 951 eV, respectively. Besides, a...

These reference pages contain tips and techniques that are designed to help both the novice and advanced XPS user. The presence of the well known shake-up satellite found in Cu 2p spectra as an indication of the presence of Cu (II) species is well known.

2022年7月21日 · We report on an original full ab initio quantum molecular approach designed to simulate Cu 2p X-ray photoelectron spectra. The description includes electronic relaxation/correlation and spin–orbit ...
