Transport properties of graphene quantum dots
Jhon W. Gonzalez, Monica Pacheco, Luis Rosales +1
In this work we present a theoretical study of transport properties of a double crossbar junction composed by segments of graphene ribbons with different widths forming a graphene…
Flat Bands in Slightly Twisted Bilayer Graphene
E. Suárez Morell, J. D. Correa, P. Vargas +2
The bands of graphite are extremely sensitive to topological defects which modify the electronic structure. In this paper we found non-dispersive flat bands no farther than 10 meV…
Fano and Dicke effects and spin polarization in a double Rashba-ring system side coupled to a quantum wire
V. M. Apel, P. A. Orellana, M. Pacheco
The electronic transport in a system of two quantum rings side-coupled to a quantum wire is studied via a single-band tunneling tight-binding Hamiltonian. We derived analytical exp…
Transport properties of graphene nanoribbon heterostructures
L. Rosales, P. Orellana, Z. Barticevic +1
We study the electronic and transport properties of heterostructures formed by armchair graphene nanoribbons with intersections of finite length. We describe the system by a tight-…
Transport modulation of graphene nanoribbons with side-attached organic molecules
L. Rosales, M. Pacheco, Z. Barticevic +2
In this work we address the effects on the conductance of graphene nanoribbons (GNRs) at which organic molecules are side-attached on the ribbon ends. For simplicity, only armchair…
Coulomb interaction effects on the electronic structure of radial polarized excitons in nanorings
Z. Barticevic, M. Pacheco, J. Simonin +1
The electronic structure of radially polarized excitons in structured nanorings is analyzed, with emphasis in the ground-state properties and their dependence under applied magneti…
