Abstract:
The atomic and electronic structures of metal-rich noncentrosymmetric zirconium oxide synthesized by the ion beam sputtering of a metallic target in an oxygen atmosphere has been studied by X-ray photoelectron spectroscopy, Raman scattering, spectral ellipsometry, and quantum-chemical simulation. It has been established that ZrO$_{x<2}$ consists of ZrO$_2$, metallic Zr, and zirconium suboxides ZrO$_y$. The stoichiometry parameter of ZrO$_y$ has been estimated. It has been shown that the optical properties of ZrO$_{x<2}$ are determined by metallic Zr. A model of fluctuation of the width of the band gap and a potential for electrons and holes in ZrO$_{x<2}$ based on spatial fluctuations of the chemical composition has been proposed.
