the band structure of GaAs in a simple cubic lattice cell (ibrav=1), I searched
from the internet the coordinates of X-point in the first Brillouin zone are 2pi/a(0,0,1)
or 2pi/a(1,0,0), but both results show that band gap occurs at G and X points
simultaneously, it seems to me that the X is equivalent to G, can you tell me the
correct X point coordinates which give me the reasonable result. </span><span lang="EN-US" style="font-size: 12pt; font-family: Cambria, serif;">The input files
