Yambo Community Forum

Dear developer，
When I used yambo to calculate the energy band, BOLTZ interpolation method was used in the input file, but NN was displayed at the end of the output file, which definitely affected the generated energy band gap. I wanted to use BOLTZ method to change the temperature at this step in order to obtain the energy band value at different temperatures, but such changes would always occur. Need your help! Hope to reply soon! Looking forward to your reply！

Dear Tom,

please sign your post with your name and affiliation, this is a rule of the forum. You can do it once for all by filling the signature in your user profile.

The switch to NN happens because you are dealing with a spinorial calculation, and tin this case the NN algorithm is used.
In any case, it is not clear what are trying to calculate, as temperature effects cannot be accounted at the interpolation step.

To account temperature effects, you can have a look at this tutorial:
