我们采用密度泛函理论和动力学平均场理论相结合的方法研究了稀土倍半氧化物和二氧化物的电子结构。我们集中在核心能级的光电子能谱上,特别地,我们说明了这些光谱如何反映4f轨道的整数或分数填充。我们将计算结果与我们早先对鳗系氧化物的计算结果进行了比较,并分析了为什么鳗系化合物的芯能级光谱对5f轨道的填充具有显著降低的敏感性。
We employ a combination of the density-functional theory and the dynamical mean-field theory to study the electronic structure of selected rare-earth sesquioxides and dioxides. We concentrate on the core-level photoemission spectra, in particular, we illustrate how these spectra reflect the integer or fractional filling of the 4f orbitals. We compare the results to our earlier calculations of actinide dioxides and analyze why the core-level spectra of actinide compounds display a substantially reduced sensitivity to the filling of the 5f orbitals.
