Fermi velocity
« on: June 11, 2020, 04:01 »
Dear Sir,

 I know it is easy to obtian the fermi velocity at a specific k point from the tutorial.

However,  how to calculate and plot the Fermi verlocity in 2D and 3D BZ space like the attachment of MgB2 ?   

Thank you so much.

There is a FermiSurface analysis object:

When opening the result in the Viewer analyzer in nanolab then open the "Fermi Surface" menu.
This will allow you to tick on "color by gradient" and choose a suitable colormap.
An example for Ruthenium of Fermi-surfaces and the contribution from individual bands can be seen here:
