Dear all,
Dose anybody have idea about the structural geometry about alfa-Al2O3 ? Should we use the rhombohedral or hexagonal primitive cell for ABINIT calculation of elastic constant?
I followed the instruction on webpage http://cst-www.nrl.navy.mil/lattice/struk/d5_1.html.
But still not sure about that. Your suggestion is welcome.

Best,
W.G.Zhang
