Abstract:
New nanomeshes with closed holes based on bilayer graphene twisted by 30$^\circ$ 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 30$^\circ$ 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 30$^\circ$ Moiré Graphene Bilayers with Folded Holes.
