Moiré Diamones: New Diamond-like Films of Semifunctionalized Twisted Graphene Layers.

We proposed novel carbon nanostructures based on a twisted few-layered graphene with one side passivated by hydrogen or fluorine: Moiré diamones on graphene. The presence of a dangling bond at the bottom layer of diamones leads to the appearance of spin density localization, which can be tuned by the variation of the twist angle with the following formation of Moiré diamones. The spin-polarized nature of electronic density distribution was obtained and discussed in detail on the basis of ab initio calculations. Such a feature makes Moiré diamones a promising key element in the field of controllable spintronic devices.
