Hi, i have problems understanding the Brilluoin zone to the bcc lattice
First, i wonder what the distances are, from the origo to the brillouin zone plane borders.
I firts thought it would be half the distance of the basis vectors (mine are 2pi/a, where a is my lattice constant, BUT its only true for 2-D calculations for square lattices.
I know that the distances in 3D should be |G-vector|/2, and i take the smallest possible G.
But i still don't know
ANyone who knows how to find the distances from origo to the first BZ zone boundaries, knowig that the basis vector in the reciprocal space is 2pi/2?are they all the same??
