I am trying to understand 3D Si dispersion relations and reciprocal lattice vectors. My confusion is that when I look at dispersion relations the wave vector typically is normalized from 0 to 1 by a/2pi. I thought the edge of the first BZ was pi/a. Is this correct or is it 2pi/a for a diamond lattice? Also, the reciprocal lattice would be 2Npi/a where N is an integer correct?(adsbygoogle = window.adsbygoogle || []).push({});
