Indirect band gap in graphene from modulation of the Fermi velocity
Jonas R. F. Lima, F. Moraes
In this work we study theoretically the electronic properties of a sheet of graphene grown on a periodic heterostructure substrate. We write an effective Dirac equation, which incl…

Effects of rotation in the energy spectrum of
Jonas R. F. Lima, Julio Brandao, Marcio M. Cunha +1
In this paper, motivated by the experimental evidence of rapidly rotating molecules in fullerite, we study the low-energy electronic states of rotating fullerene within a…

Landau levels, self-adjoint extensions and Hall conductivity on a cone
A. Poux, L. R. S. Araujo, C. Filgueiras +1
In this work we obtain the Landau levels and the Hall conductivity at zero temperature of a two-dimensional electron gas on a conical surface. We investigate the integer quantum Ha…
