title: Bilayered graphene as a platform of nanostructures with folded edge holes.
abstract: The stability and the electronic properties of new AB-stacking and moiré bilayer graphene superlattices with closed edge nanoholes are studied using DFT calculations. The closing of the edges is made of C-C bonds that form after folding the borders of the holes. Superlattices with periodic hexagonal symmetry are considered in more detail. The electronic band structure of the nanomeshes has metallic to semiconductor characteristics, depending not only on the size of the holes and the distance between them, but also on the hole shape. Bilayered graphene is considered as a platform for the engineering of nanostructures with folded edge holes.
