  • Disorder effect on the density of states in Landau quantized graphene 
    Dóra, Balázs (Физика низких температур, 2008)
    We have studied the effect of gaussian potential (on-site) and unidirectional bond disorder on the density of states (DOS) of Landau quantized graphene. The broadening of the Landau levels weakly depends on energy and ...
  • Edge states in quantum Hall effect in graphene (Review Article) 
    Gusynin, V.P.; Miransky, V.A.; Sharapov, S.G.; Shovkovy, I.A. (Физика низких температур, 2008)
    We review recent results concerning the spectrum of edge states in the quantum Hall effect in graphene. In particular, a special attention is payed to the derivation of the conditions under which gapless edge states exist ...
  • Effect of next-to-nearest neighbor hopping on electronic properties of graphene 
    Suprunenko, Y.F.; Gorbar, E.V.; Sharapov, S.G.; Loktev, V.M. (Физика низких температур, 2008)
    In the tight-binding approximation, we take into account the next-to-nearest neighbor hopping in graphene that leads to nonrelativistic-like corrections in its low energy spectrum. The electronic density of states in a ...
  • Electrostatic screening and Friedel oscillations in semiconducting nanotubes 
    Chaplik, A.V.; Magarill, L.I.; Vitlina, R.Z. (Физика низких температур, 2008)
    In 3D and 2D electronic systems the singular contribution to the static permittivity ε (Kohn singularity) is a small correction to the regular part of ε but it results in the leading term in asymptotic behavior of ...
  • Giant magnetization of a superconductor–two-dimensional electron gas–superconductor structure 
    Romanovsky, I.A.; Bogachek, E.N.; Krive, I.V.; Landman, U. (Физика низких температур, 2008)
    Superconductivity induced phase-controlled mesoscopic magnetic effects in a two-dimensional electron gas that bridges two superconducting reservoirs are investigated. Giant paramagnetic response of the junction, occuring ...
  • Graphene and graphene-based nanostructures 
    Krive, I.V.; Loktev, V.M.; Shekhter, R.I. (Физика низких температур, 2008)
    This issue of the journal «Fizika Nizkikh Temperatur» is dedicated to the discovery of graphene — a monolayer graphite — in 2004.
  • Index of refraction of a photonic crystal of carbon nanotubes and homogenization of optically anisotropic periodic composites 
    Gumen, L.N.; Krokhin, A.A. (Физика низких температур, 2008)
    We consider the long-wavelength limit for a periodic arrangement of carbon nanotubes. Using the Fourier expansion method we develop an effective-medium theory for photonic crystal of aligned optically anisotropic cylinders. ...
  • Local heating method for growth of aligned carbon nanotubes at low ambient temperature 
    Dittmer, S.; Mudgal, S.; Nerushev, O.A.; Campbell, E.E.B. (Физика низких температур, 2008)
    We use a highly localised resistive heating technique to grow vertically aligned multiwalled nanotube films and aligned single-walled nanotubes on substrates with an average temperature of less than 100°C. The temperature ...
  • Luttinger liquid and polaronic effects in electron transport through a molecular transistor 
    Skorobagat’ko, G.A.; Krive, I.V. (Физика низких температур, 2008)
    Electron transport through a single-level quantum weakly dot coupled to Luttinger liquid leads is considered in the master equation approach. It is shown that for a weak or moderately strong interaction the differential ...
  • Microwave induced forward scattering and Luttinger liquid interferences in magnetically confined quantum wires 
    Nogaret, Alain; Portal, Jean-Claude; Beere, H.E.; Ritchie, D.A.; Phillips, Chris (Физика низких температур, 2008)
    We report on the photoresistance of a magnetic quantum wire obtained by applying a gradient of magnetic field to a two-dimensional electron gas. Electron transmission through the magnetic wire increases by an order of ...
  • Semiclassical approach to the description of the basic properties of nanoobjects 
    Kornyushin, Y. (Физика низких температур, 2008)
    Present paper is a review of results, obtained in the framework of semiclassical approach in nanophysics. Semiclassical description, based on Electrostatics and Thomas–Fermi model was applied to calculate dimensions of ...
  • Spectral function of graphene with short-range impurity centers 
    Skrypnyk, Yu.V.; Loktev, V.M. (Физика низких температур, 2008)
    Spectral function of graphene with point substitutional defects is calculated for different impurity concentrations. It is demonstrated that features in the spectral function of graphene observed in ARPES experiments can ...
  • The Berry phase in graphene and graphite multilayers 
    Mikitik, G.P.; Sharlai, Yu.V. (Физика низких температур, 2008)
    We discuss the electron energy spectra and the Berry phases for graphene, a graphite bilayer, and bulk graphite allowing for a small spin-orbit interaction. If an electron orbit in the Brillouin zone surrounds several Dirac ...
  • Tight-binding study of nonmagnetic-defect-induced magnetism in graphene 
    Kumazaki, H.; Hirashima, D.S. (Физика низких температур, 2008)
    This review describes a study of nonmagnetic-defect-induced magnetism of graphene on the basis of a tight-binding model. A vacancy induces a quasilocalized impurity state at the chemical potential around itself, and it ...
  • Toward theory of quantum Hall effect in graphene 
    Gorbar, E.V.; Gusynin, V.P.; Miransky, V.A. (Физика низких температур, 2008)
    We analyze a gap equation for the propagator of Dirac quasiparticles and conclude that in graphene in a magnetic field, the order parameters connected with the quantum Hall ferromagnetism dynamics and those connected ...

    Sitenko, Yu.A.; Vlasii, N.D. (Физика низких температур, 2008)
    The influence of a topological defect in graphene on the ground state of electronic quasiparticle excitations is studied in the framework of the long-wavelength continuum model originating in the tightbinding approximation ...
