Band structure and gaps of triangular graphene superlattices.
نویسندگان
چکیده
The general properties of long wavelength triangular graphene superlattices are studied. It is shown that Dirac points with and without gaps can arise at a number of high-symmetry points of the Brillouin zone. The existence of gaps can lead to insulating behaviour at commensurate fillings. Strain and magnetic superlattices are also discussed.

Energy gap of Kronig-Penney-type hydrogenated graphene superlattices
The electronic structure of graphene-graphane superlattices with armchair interfaces is investigated with first-principles density-functional theory. By separately varying the widths, we find that the energy gap Eg is inversely proportional to the width of the graphene strip and that the gap increases as the hydrogenated strip becomes wider due to the enhanced confinement effect. It is further ...
متن کاملTopological features and gauge fields in graphene superlattices. Detecting Topological Currents in Graphene Superlattices
The quest for crystals whose electronic bands show non trivial topological features has not ceased since the discovery of the Quantum Hall Effect. The amazing current quantization in QHE devices can be traced back to edge states which emerge from non trivial electronic structures[1, 2]. Topological properties are typically associated to integer numbers, so that they are quite robust against per...
متن کاملHighly anisotropic Dirac cones in epitaxial graphene modulated by an island superlattice.
We present a new method to engineer the charge carrier mobility and its directional asymmetry in epitaxial graphene by using metal cluster superlattices self-assembled onto the moiré pattern formed by graphene on Ir(111). Angle-resolved photoemission spectroscopy reveals threefold symmetry in the band structure associated with strong renormalization of the electron group velocity close to the D...
متن کاملThe effect of material nonlinearity on the band gap for TE and TM modes in square and triangular lattices
In this article, by using the method of finite difference time domain (FDTD) and PML boundary conditions, we have studied the photonic band gaps for TE and TM modes in square and triangular lattices consisting of air holes in dielectric medium and compared the results. In addition, the effect of nonlinearity of the photonic crystal background on the photonic band gaps and comparison with the re...
متن کاملComparison of Normal and Inverted Band Structure HgTe/CdTe Superlattices for Very Long Wavelength Infrared Detectors
The type III band alignment of HgTe/CdTe superlattices leads to the interesting possibility of achieving very long wavelength infrared (VLWIR) (15 μm and longer) cutoff wavelengths with either normal (HgTe layer thickness less than about 70 Å for CdTe layer thickness of 50 Å) or inverted (HgTe thickness greater than about 70 Å) band structures. The inverted band structure superlattices promise ...
