Doping evolution of the electronic structure of Sr-doped NdNiO<sub>2</sub>

ORAL

Abstract

Since the discovery of high-temperature superconductivity in cuprates, many efforts have been devoted to reproduce their electronic structure by proper material engineering. Nickel oxides occupy a prominent place since they are theoretically proposed to host superconductivity. After intense research, superconductivity has been recently discovered in Sr-doped NdNiO2. Theory and experiments have been conducted to understand the electronic structure of the parent compound NdNiO2. Yet, spectroscopic information about how Sr-doping affects the electronic states is still lacking. In this presentation, I will discuss the doping evolution of the electronic structure, as revealed by our recent experimental results from x-ray absorption spectroscopy (XAS) and resonant inelastic x-ray scattering (RIXS).
