Correlation effects in Auger spectra of Ni and Cu nanoclusters
چکیده انگلیسی

Results of experimental research of exciton-like two-hole states in nanoclusters of narrow-band metals (Ni, Cu) on surface of high-oriented pyrolitic graphite by X-ray photoelectron and Auger electron spectroscopy are presented. It was found that the evolution of the electronic structure in Ni nanoclusters with the decreasing of their sizes can lead to appearance of long-living two-hole states in the valence band. One-particle and two-particle density of states are analyzed, and the Auger-electron spectra confirming the presence of the bound and localized states are obtained.


► We investigated electronic properties of Cu and Ni nanoclusters.
► We observed the narrowing of LVV Auger spectrum in Ni clusters.
► Long-living two-hole states in the valence band of Ni are observed.
