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…
Lattice Thermal Conductivity of 2D Nanomaterials: A Simple Semi-Empirical Approach
R. M. Tromer, I. M. Felix, L. F. C. Pereira +3
Extracting reliable information on certain physical properties of materials, like thermal behavior, such as thermal transport, which can be very computationally demanding. Aiming t…
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…
Wave transmission and its universal fluctuations in one-dimensional systems with Lévy-like disorder: Schrödinger, Klein-Gordon and Dirac equations
Anderson L. R. Barbosa, Jonas R. F. Lima, Luiz Felipe C. Pereira
We investigate the propagation of waves in one-dimensional systems with Lévy-type disorder. We perform a complete analysis of non-relativistic and relativistic wave transmission su…
Suppression of coherent thermal transport in quasiperiodic graphene-hBN superlattice ribbons
Isaac M. Felix, Luiz Felipe C. Pereira
Nanostructured superlattices are promising materials for novel electronic devices due to their adjustable physical properties. Periodic superlattices facilitate coherent phonon the…
