Engineering Delocalization in Graphene Nanoribbons via Quasiperiodic Edges and Electronic Interactions
Diego B. Fonseca, Anderson L. R. Barbosa, Luiz Felipe C. Pereira
We investigate localization effects in zigzag graphene nanoribbons with quasiperiodic Fibonacci-type edge extensions, accounting for electron-electron interactions. We employ a tig…
Spin Hall effect in electronic Lévy glasses: Enhanced spin current generation in the superdiffusive regime
Diego B. Fonseca, Luiz Felipe C. Pereira, Anderson L. R. Barbosa
In spintronics, both electronic charge and spin are used to process and store information. Generation, manipulation, and detection of spin currents are essential for the developmen…
Lévy flight for electrons in graphene in the presence of regions with enhanced spin-orbit coupling
Diego B. Fonseca, Anderson L. R. Barbosa, Luiz Felipe C. Pereira
We propose an electronic Lévy glass built from graphene nanoribbons in the presence of regions with enhanced spin-orbit coupling. Although electrons in graphene nanoribbons present…
Orbital Hall effect in mesoscopic devices
Diego B. Fonseca, Lucas L. A. Pereira, Anderson L. R. Barbosa
We investigate the orbital Hall effect through a mesoscopic device with momentum-space orbital texture that is connected to four semi-infinite terminals embedded in the Landauer-Bü…
A Lévy flight for electrons in graphene: superdiffusive-to-diffusive transport transition
Diego B. Fonseca, Luiz Felipe C. Pereira, Anderson L. R. Barbosa
In this work we propose an electronic Lévy flight device, analogous to a recent optical realization. To that end, we investigate the transmission of electrons in graphene nanoribbo…
