Abstract

The effective valence of copper in the region of its concentration up to x = 0.25 in Cu_xZrSe₂ has been determined based on an analysis of binding energies of the Zr3d and Se3d core levels and the electromotive forces from an electrochemical experiment for Cu_xZrSe₂, as a function of Cu concentration x. It has been shown that the domination of covalent bonding between copper and the ZrSe₂ host lattice within this concentration range results in a notable reduction in the effective valence of copper in comparison to its nominal value.
