Abstract: | We monitored the resonant behavior of the Ni d satellite peaks in the valence band photoemission spectra of NiPS3 at photon energies immediately below and immediately above the Ni3p threshold. The observed resonance gives an unequivocal identification of the satellite peaks and of the corresponding main Ni d features. The study of the electronic structure of this material and of the related compounds FePS3 and HgPS3 was extended to unoccupied states by means of partial-yield synchrotron-radiation photoemission spectroscopy. |
