Can one also get the band-structures as a function of k where k can be anywhere in the first Brillouin-zone?

Hej alla,

in the database, it seems to me, that “only” band-structures along the k-path are depicted / accessible; Whereas, in order to determine the density of states, one needs the k-dependence of the bands for all k-vectors within the first Brillouin-zone.

My question: Is there the possibility to gain access to the energy-bands for arbitrary k-vectors within the first Brillouin-zone from the website, s.t. one can also apply these band-structures to work with Green-function-techniques?

Hi Sebastian.

I think what you are looking for is achievable with this:

rester.get_bandstructure_by_material_id(material_id, line_mode=True)

where line_mode should be set to False to get the uniform band structure.

Hej fraricci,

thank you very much for your answer! Having hardly worked with DFT before, can you maybe give me a good reference for a step-by-step-guide on how to use this piece of code that you mentioned? Can you tell me whether this would be a proper guide for me to follow, in order to learn the subject? (I feel a little bit lost in the ocean. :'-) )
