I am trying yo build an illite slit pore on pymatgen. I would like to have two illite slabs separated by a distance of 20 angstroms (this will be my pore size). I was able to build a slab, but how can I replicate it on pymatgen and have this two slabs separated by a specified distance? I don’t want to have vacuum above the upper slab and vacuum below the bottom slab (just between the two slabs). I uploaded a picture of my illite slab.
I appreciate any help on this.
