摘要
在BaFe2As2的不同位置掺杂,提供稳定的化学压力和调节载流子,一直是一个热门的研究课题。本文采用密度泛函理论(DFT)方法对mg - ba等价取代BaFe2As2进行了全面的理论研究。所有DFT计算均使用GTH-PBE/ dzpv - molopt - sr - gth进行。通过对dft计算的波函数进行穷尽后处理,得到了HOCO、ELF、BO、电荷居数、LOL-π、IRI等电子性质。到目前为止,基于生成的波函数对新型mg掺杂BaFe2As2的电子性质的研究还很少,因此我们的研究结果和相应的方法将有利于铁基超导体家族的研究。
A Density Functional Theory Study of the Electronic Properties of Isovalent Mg-Substituting-Ba for BaFe2As2
Doping at various positions of BaFe2As2, providing stable chemical pressure and adjusting carriers, has always been a popular research topic. In the work, we conducted a comprehensive theoretical study on the isovalent Mg-substituting-Ba for BaFe2As2 by using the density functional theory (DFT) method. All DFT calculations were performed with the set of GTH-PBE/DZVP-MOLOPT-SR-GTH. By exhaustively post-processing the DFT-calculated wavefunction, the electronic properties such as HOCO, ELF, BO, charge population, LOL-π, IRI, etc., were reported. Up to now, the investigations of electronic properties for novel Mg-doped BaFe2As2 based on the generated wavefunction are barely, thus it is well expected that our results with the corresponding method will benefit the research of the Fe-based superconductors family.
