按照VESTA Manual中写的
”CHG stores lattice vectors, atomic coordinates, and total charge densities multiplied by the unit-cell volume, V. ... When these files are read in to visualize isosurfaces and sections, data values are divided by V in the unit of bohr^3. The unit of charge densities input by VESTA is, therefore, bohr^-3."CHGCAR文件中的electron density单位是eV*angstrom^3, 我的试着换算了一下CHGCAR中的electron density的第一个值0.41894056779E+04
file:///C:/Users/LIJIAM~1/AppData/Local/Temp/msohtmlclip1/01/clip_image002.png
这个值和VESTA的输出cube文件的 第一个值明显对不上,有老师知道我的换算中少算了什么值吗 |
