Аннотация: It is shown that lines of adsorbed hydrogen pair atoms divide the graphene sheet into strips and form hydrogen-based superlattice structures (2HG-SL). We show that the formation of 2HG-SL changes the electronic properties of graphene from semimetal to semiconductor. The electronic spectra of "zigzag" (n,0) 2HG-SL is similar to thatПоказать полностьюof (n,0) carbon nanotubes and have a similar oscillation of band gap with n, but with nonzero minimal values. The composite dual-periodic (n,0)+(m,0) 2HG-SLs of zigzag strips are analyzed, with the conclusion that they may be treated as quasi-two-dimensional heterostructures.
