N2 - The electronic properties and charge states of atoms in four hafnium-based compounds, with general formulae HfIrxBy, namely HfIr3, Hf2Ir5B2, HfIr3Bx, and HfB2, have been studied using X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy (UPS) and calculations based on density functional theory (DFT). It was stated that Hf atoms have a partial positive charge, whereas Ir and B atoms have a partial negative charge in these compounds. Both theoretical and experimental analyses of the electronic structure near the Fermi level showed that all compounds exhibit metallic behavior. The experimental and theoretical work function of the HfIrxBy compounds was determined to lie in the range 4–5 eV.
