[求助] 金属间化合物价电子数怎么求?

看到CASTEP做第一性原理计算的好几篇文章算金属性,利用了价电子数N求的,不知道这个数值怎么来的,CASTEP计算结果里面的电子数应该不是公式里面的数值,好像在结果文件没看到所谓的价电子数,我上传了截图,看看了解这方面的虫友 帮忙看看。

where Df is the DOS value at the Fermi level in unit states/eV·cell, and T is the temperature; nm and ne are the thermal excited electrons and valence electron density of the cell, respectively; kB is the Boltzmann constant. ne is calculated by ne = N/Vcell, N is the total number of valence electrons and Vcell is the cell volume. The related parameters and calculated results as shown in Table 6, we can observed that fm increases in the following sequence: MgLa < MgSc < MgY. Thus, the maximal and minimal “metallicity” correspond to the MgY and the MgLa, respectively
