▎ 摘　　要

Unique band structure peculiarities of graphene imply that near Fermi level electrons are described by two-dimensional Dirac equation for massless particles. We investigate how these peculiarities manifest in electron-hole pairing and properties of indirect magnetoexcitons in two spatially separated, independently gated graphene layers. For electron-hole pairing, we derive asymptotical expressions for the gap in energy spectrum and discuss system behavior at various controlling parameters. We derive dispersion relations for magnetoexcitons and their effective-mass decompositions, and also discuss a possibility of magnetoexcitonic super-fluidity. The systems under consideration can reveal coherent properties, dissipationless currents and Josephson phenomena at room temperature. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
