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 presen…
