Creation of 2D and 3D structures in same program

Respected Sir/Mam,

I want to build a graphene layer (2-D) on a Silicon substrate (3-D) in the same program. Is this possible cos when we explicitly mention dimension 2 command in the beginning it removes the 3D option and if it is not mentioned a default 3D (only) is considered. Please let me know if they can be merged in the same program.

Thanks and regards

Sure, create a custom lattice for graphite and apply it to a thin
region, effectively limiting it to a single plane of graphene. Then
create a big region underneath and create the Si lattice.

You can run a 3d simulation and create or import
atoms that are part of 2d structures like a graphene
