How do I get the data near the VBM and CBM points？

[sugarandgugu]

Is there having an API to get these points？which I need to calculate the curvature.

hello?

You can pull the entire pymatgen band structure object with MPRester.get_bandstructure_by_material_id, and then use the get_cbm() and get_vbm() methods. The pymatgen object documentation can be found here:

https://pymatgen.org/pymatgen.electronic_structure.bandstructure.html#module-pymatgen.electronic_structure.bandstructure

hi!I use your method to get the class BandStructureSymmLine,but the class hasn't the eigenvals Attributes. Is the points near the CBM in this attributes?

[sugarandgugu]

I mean the points near the CBM and VBM.

You can use bandstructure.bands to get the full list of eigenvalues.

OK!Merci Beaucoup
