I want to make Al/SiC structure in material studio. how can i do it? there is pure Al structure and SiC structure in material studio software. I want to delete group atoms from bulk of Al and replace them with SiC particles .
First, you have to create Al bulk structure in material studio and then create 1x1x1 supercell. Now you can delete a group of Al atoms as you wish. After removing Al atoms, replace it with SiC and apply symmetry.
Have you explored packmol (http://m3g.iqm.unicamp.br/packmol/home.shtml). Although its tailored towards molecular systems, you may find it has some advantages over the Materials Studio builder.
