论文摘要
使用密度功能理论（DFT）计算了两个不同的基于Fe的超导材料FESE和FETE的电子能量损失（ELNES）。 Fe K边缘吸收光谱由几个特征组成，其起源是根据成分原子状态的部分密度彻底描述的。在这里，我们包括“核心孔效应”，并发现吸收光谱发生了巨大变化。我们的结果包括核心孔效应与实验X射线吸收近边缘结构（XANES）结果非常匹配文献。
Electron energy loss near edge spectra (ELNES) has been calculated for two different Fe based superconducting material FeSe and FeTe using density functional theory (DFT). Fe K-edge absorption spectra consist of several features, origins of which are thoroughly described in light of partial density of states of constituent atoms. Here we have included "core-hole effect" and found drastic change in absorption spectra. Our results including core hole effect matches very well with experimental X-ray Absorption Near Edge Structure (XANES) results available in literature.
