Phase diagram for quantum Hall states in graphene
Jianhui Wang, A. Iyengar, H. A. Fertig +1
We investigate integer and half-integer filling states (uniform and unidimensional stripe states respectively) for graphene using the Hartree-Fock approximation. For fixed filling…
Conductance Through Graphene Bends and Polygons
A. Iyengar, T. Luo, H. A. Fertig +1
We investigate the transmission of electrons between conducting nanoribbon leads oriented at multiples of 60 degrees with respect to one another, connected either directly or throu…
Vacancy induced magnetism in graphene and graphene ribbons
J. J. Palacios, J. Fernandez-Rossier, L. Brey
We address the electronic structure and magnetic properties of vacancies and voids both in graphene and graphene ribbons. Using a mean field Hubbard model, we study the appearance…
Excitations from Filled Landau Levels in Graphene
A. Iyengar, Jianhui Wang, H. A. Fertig +1
We consider graphene in a strong perpendicular magnetic field at zero temperature with an integral number of filled Landau levels and study the dispersion of single particle-hole e…
