[ase-users] Cutting tdirections hrough a bulk cubic unit cell to get 111 surface and Orthorombic cell

[Isabela Man]

Dear all,
Because it might be faster to ask like this.
I want to cut through a cubic unit cell (oxide) such as to get the 111
surface. If anyone could help me with the directions I should cut
through, such as to get an ORTHOROMBIC cell I would be very thankfull.
I am using the command : slab = cut(bulk, a = [x1,y1,z1], b =
[x2,y2,z2], c = [x3,y3,z3])
Thank you in advance
