FCC 111 Surface

Post by amorri21 » Thu Feb 27, 2014 10:43 pm

Hi,
I'm trying to make a 111 FCC surface for some surface relaxation studies of a slab and am having a hard time creating the proper super cell. I can easily make (shown below) the 100 surface, but the 111 surface is eluding me. Any tips/help would be greatly appreciated, I'm (obviously) new at this!

Thanks.
