BaCu $_2$ As $_2$和SrCu $_2$ As $_2$的电子结构：sp带金属
Electronic structure of BaCu$_2$As$_2$ and SrCu$_2$As$_2$: sp-band metals
摘要：
用密度泛函方法研究了ThCr $_2$ Si $_2$结构BaCu $_2$ As $_2$和SrCu $_2$ As $_2$的电子结构. Cu $d$轨道位于3 eV和更高的结合能处，因此是化学惰性的，在费米能附近几乎没有贡献。这些材料具有中等的态密度，具有大的费米面和低的各向异性的sp带金属。
英文摘要：
The electronic structures of ThCr$_2$Si$_2$ structure BaCu$_2$As$_2$ and SrCu$_2$As$_2$ are investigated using density functional calculations. The Cu $d$ orbitals are located at 3 eV and higher binding energy, and are therefore chemically inert with little contribution near the Fermi energy. These materials are moderate density of states, sp-band metals with large Fermi surfaces and low anisotropy.
