Thanks for your reply.
Actually I know how to draw the BZ in 2D-lattice, it's just like the WZ-cell.
How do I apply this to calculate the shortest distance to the 1st BZ for a BCC or FCC?
Is it always half of the reciprocal lattice vectors b_i? Or is that specific for a BCC?
Do I understand...
Hi, I just can't understand the basics with BZ.
How do I find the shortest distance to the BZ boundary, how do I compare the electron energy between the last electron in the 1st BZ with the first electron in the 2nd BZ?
I think I need a visual how to calculate these things, does anyone...
