Controlling the energy gap of graphene by Fermi velocity engineering
Jonas R. F. Lima
The electronic structure of a single-layer graphene with a periodic Fermi velocity modulation is investigated by using an effective Dirac-like Hamiltonian. In a gapless graphene or…

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…
