A 50/50 electronic beam splitter in graphene nanoribbons as a building block for electron optics
Leandro R. F. Lima, Alexis R. Hernández, Felipe A. Pinheiro +1
Based on the investigation of the multi-terminal conductance of a system composed of two graphene nanoribbons, in which one is on top of the other and rotated by 60 degrees, we pro…
Nonlinear conductance in a ballistic Aharonov-Bohm ring
Alexis R. Hernández, Caio H. Lewenkopf
The nonlinear electronic transport properties of a ballistic Aharonov-Bohm ring are investigated. It is demonstrated how the electronic interaction breaks the phase rigidity in a t…
Nonlinear electronic transport in nanoscopic devices: Nonequilibrium Green's functions versus scattering approach
Alexis R. Hernández, Caio H. Lewenkopf
We study the nonlinear elastic quantum electronic transport properties of nanoscopic devices using the Nonequilibrium Green's function (NEGF) method. The Green's function method al…
Adiabatic Charge Pumping through Quantum Dots in the Coulomb Blockade Regime
A. R. Hernández, F. A. Pinheiro, C. H. Lewenkopf +1
We investigate the influence of the Coulomb interaction on the adiabatic pumping current through quantum dots. Using nonequilibrium Green's functions techniques, we derive a genera…
