Abstract
Substrate-induced effects in the creation and decay of 2p core excitations of K+ and Clâ in ultrathin films of KCl on Cu(1â0â0) surface have been studied using photoelectron, photoabsorption and resonant Auger spectra, excited by synchrotron radiation. The measurements were performed on different overlayers ranging from sub-monolayer coverages up to continuous thick films. It is demonstrated that the formation and decay of core excitations in thin films of KCl at Cu(1â0â0) surface is strongly influenced by the hybridization of excited states of K+ or Clâ origin with the metal substrate, which leads to the delocalization of the excited electron from the absorption site.
