Title: Bandstructure
Post by: achal18895 on November 22, 2018, 05:45

Hello
If band-structure has only straight lines by some brillouin zone. Is it correct or not?
but if i am using another brillouin zone then it comes zero band-gap.

Hello
I have attach the file of band structure. In this it has only straight lines, is it possible that this type of band structure comes of hetero-structure?

If you did the calculation for a heterostructure, this band structure corresponds to the heterostructure.

Yes Sir, I'm doing these calculations for the heterostructure.

There is not much to say about your band structure without seeing the actual python script with the structure of the system and the computational settings.
