Layer-Resolved Quantum Transport in Twisted Bilayer Graphene: Counterflow and Machine Learning Predictions
Matheus H. Gobbo Kuhn, L. A. Silva, D. A. Bahamon
The layer-resolved quantum transport response of a twisted bilayer graphene device is investigated by driving a current through the bottom layer and measuring the induced voltage i…
Fast Fourier-Chebyshev approach to real-space simulations of the Kubo formula
Santiago Giménez de Castro, João M. Viana Parente Lopes, Aires Ferreira +1
The Kubo formula is a cornerstone in our understanding of near-equilibrium transport phenomena. While conceptually elegant, the application of Kubo's linear-response theory to inte…
Chirality probe of twisted bilayer graphene in the linear transport regime
Dario A. Bahamon, Guillermo Gómez-Santos, Dmitri K. Efetov +1
We propose minimal transport experiments in the coherent regime that can probe the chirality of twisted moiré structures. We show that only with a third contact and in the presence…
Efficient Chebyshev polynomial approach to quantum conductance calculations: Application to twisted bilayer graphene
Santiago Giménez de Castro, Aires Ferreira, D. A. Bahamon
In recent years, Chebyshev polynomial expansions of tight-binding Green's functions have been successfully applied to the study of a wide range of spectral and transport properties…
A critical analysis on the sensitivity enhancement of surface plasmon resonance sensors with graphene
Aline dos S. Almeida, D. A. Bahamon, Nuno M. R. Peres +1
The use of graphene in surface plasmon resonance sensors, covering a metallic (plasmonic) film, has a number of demonstrated advantages, such protecting the film against corrosion/…
Second-harmonic generation enhancement in monolayer transition-metal dichalcogenides by an epsilon-near-zero substrate
Pilar G. Vianna, Aline dos S. Almeida, Rodrigo M. Gerosa +2
Monolayer transition-metal dichalcogenides (TMDCs) present high second-order optical nonlinearity, which is extremely desirable for, e.g., frequency conversion in nonlinear photoni…
