Thank you!
That's quite interesting that we can reconstruct the band structure from only information at \Gamma
Still people plot the diagrams in the particular paths along irreducible zones. You say
Why these are more important?
Thanks again
When energy levels for a lattice are constructed the Bloch wave vector is evaluated along the edges of the irruducible zone. Like \Gamma - X - M path for a square lattice.
I wonder why the calculation is NOT performed for values within the zone? And how the energy corresponding to an...
