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…
Third edge for a graphene nanoribbon: A tight-binding model calculation
D. A. Bahamon, A. L. C. Pereira, P. A. Schulz
The electronic and transport properties of an extended linear defect embedded in a zigzag nanoribbon of realistic width are studied, within a tight binding model approach. Our resu…
Tunable resonances due to vacancies in graphene nanoribbons
D. A. Bahamon, A. L. C. Pereira, P. A. Schulz
The coherent electron transport along zigzag and metallic armchair graphene nanoribbons in the presence of one or two vacancies is investigated. Having in mind atomic scale tunabil…
Quasi-energy spectra of graphene dots under intense ac field: field anisotropy and photon dressed quantum rings
P. H. Rivera, A. L. C. Pereira, P. A. Schulz
A graphene quantum dot under intense ac field and static low magnetic field is investigated. From a tight-binding perspective, applying a Fourier-Floquet transformation and renorma…
Inner and outer edge states in graphene rings: A numerical investigation
D. A. Bahamon, A. L. C. Pereira, P. A. Schulz
We numerically investigate quantum rings in graphene and find that their electronic properties may be strongly influenced by the geometry, the edge symmetries and the structure of…
Adittional levels between Landau bands due to vacancies in graphene: towards a defect engineering
A. L. C. Pereira, P. A. Schulz
We describe the effects of vacancies on the electronic properties of a graphene sheet in the presence of a perpendicular magnetic field: from a single defect to an organized vacanc…
