bandstructure显示带宽刚好为零,但是dos显示费米能级的态密度不为零(如图)还有的情况是bandstructure显示很小的带宽,但是dos显示没有带宽.还有一个问题是带宽没有出现在高对称点,所以用了很多的k点来确定bandstructure2013/0816/w130h793352_1376606975_490.jpg|bcs|2013081
VASP计算DOS的基本步骤有三步：1.对结构进行充分弛豫，也就是几何优化晶胞和原子占位，关键参数ISIF=3....
Band structure and DOS of Sapphire are calculated by ab-initial method based on the density functional theory.Pesudopotentials are applied to represent the valence electrons of Al and O.The crystal constants of Sapphire cell are very close to the experiment results after geometry optimization.For ...

Bandstructures and Density of States 能带以及态密度
The electronic energy band structure of 尾-Si 3 N4 has been calculated using the first principles LCAO method. The bottom of the Conduction Band (CB) is at 螕 and the top of the valence band (VB) is located along line. The very flat top VB along accounts for a large hole effective ...
This is a result of the special band structure of AlCl2, which introduces a strong energy dependence of the joint DOS (JDOS). The JDOS gives the density of electron–hole pairs at a given frequency (disregarding momentum conservation) and thus represents the density of final states entering ...
This GGA + U method was used to calculate the band structure and DOS. All self-consistent calculations were carried out using a convergence criterion of 10−6 eV. The geometric structures in all cases were fully optimized without any symmetry constraints using the GGA + U...
We have calculated the Energy band structure and total density of state of Co. In order to study the magnetic properties of Co,The calculation was performed in spin polarized situation. The result shows that the Co-hcp is a ferromagnetic and the electrons of localized d-orbital have a ...
