New nanomeshes with closed holes based on bilayer graphene twisted by 30A degrees are studied. It is found that such structures can have different electronic characteristics (from semiconducting to metallic) depending on the shape of holes. Comparison with the single-layer graphene meshes having holes of similar shapes demonstrates a significant difference of their electronic spectra. The meshes with triangular "folded" holes turn out to be nonmagnetic in contrast to the single-layer meshes with the same holes. The spectra of 30A degrees bilayer graphene nanomeshes exhibit numerous peaks in the electron density of states within a wide energy range. This makes such structures promising for applications in photovoltaics and optoelectronics. Features of 30A degrees Moir, Graphene Bilayers with Folded Holes.
