文獻中關於xps的相關描述如下：

The high‐resolution Mn 2p profile could be fitted within

an appropriate principle at 640.9 eV (2p3/2) and 652.6 eV

(2p1/2) which was ascribed to the binding energy of Mn2+.

The peaks located at 645.3 eV (2p3/2) and 658.1 eV (2p1/2)

indicated the presence of Mn4+（

XPS spectrum of P 2p was fitted to double peaks, that is,

132.8 and 131.8 eV, which were in line with P 2p3/2 and

P 2p1/2, respectively. There was only a pair of peaks at

162.3 eV (2p3/2) and 163.5 eV (2p1/2)16,21 for the S 2p in

Figure 1F, indicating that only one form of S existed in

MnPS3. Meanwhile, observations from the scanning

transmission electron microscopy and energy‐dispersive

X‐ray spectroscopy in Figure 1G–J verified that the Mn, P,

and S elements were homogeneously distributed in the

sample.
