<p dir="ltr">dear altruists,<br>
while finding band structure for bilayer graphene, I used "ibrav=4"<br>
now can somebody tell me why we use the value of ibrav =4 ???<br>
I think this value indicates 3D structure of graphene which is actually graphite not graphene.....it would be helpful if somebody could explain this...</p>
<p dir="ltr">thanks in advance....... </p>
