Disorder effect on the anisotropic resistivity of phosphorene determined by a tight-binding model
Carlos J. Páez, Kursti DeLello, Duy Le +2
In this work we develop a compact multi-orbital tight-binding model for phosphorene that accurately describes states near the main band gap. The model parameters are adjusted using…
Resonant tunneling through protected quantum dots at phosphorene edges
C. J. Páez, D. A. Bahamon, Ana L. C. Pereira +1
We theoretically investigate phosphorene zigzag nanorribons as a platform for constriction engineering. In the presence of a constriction at the upper edge, quantum confinement of…
Electronic transport across linear defects in graphene
C. J. Páez, J. N. B. Rodrigues, A. L. C. Pereira +1
We investigate the low-energy electronic transport across grain boundaries in graphene ribbons and infinite flakes. Using the recursive Green's function method, we calculate the el…
Current flow in biased bilayer graphene: the role of sublattices
C. J. Páez, D. A. Bahamon, Ana L. C. Pereira
We investigate here how the current flows over a bilayer graphene in the presence of an external electric field perpendicularly applied (biased bilayer). Charge density polarizatio…
Correlated random hopping disorder in graphene at high magnetic fields: Landau level broadening and localization properties
A. L. C. Pereira, C. H. Lewenkopf, E. R. Mucciolo
We study the density of states and localization properties of the lowest Landau levels of graphene at high magnetic fields. We focus on the effects caused by correlated long-range…
Splitting of critical energies in the =0 Landau level of graphene
Ana L. C. Pereira
The lifting of the degeneracy of the states from the graphene =0 Landau level (LL) is investigated through a non-interacting tight-binding model with random hoppings. A disorder…
