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…
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…
Robust signatures in the current-voltage characteristics of DNA molecules oriented between two graphene nanoribbon electrodes
Carlos J. Páez, Peter A. Schulz, Neil Wilson +1
In this work we numerically calculate the electric current through three kinds of DNA sequences (telomeric, λ-DNA, and p53-DNA) described by different heuristic models. A bias volt…
