Edge-state transport in twisted bilayer graphene
Jesús Arturo Sánchez-Sánchez, Montserrat Navarro-Espino, José Eduardo Barrios-Vargas +1
We investigate the electronic structure and transport properties of twisted bilayer graphene (TBLG) at a twist angle of . Using a combination of molecular d…
Steering the current flow in twisted bilayer graphene
Jesús Arturo Sánchez-Sánchez, Montserrat Navarro-Espino, Yonatan Betancur-Ocampo +2
A nanoelectronic device made of twisted bilayer graphene (TBLG) is proposed to steer the direction of the current flow. The ballistic electron current, injected at one edge of the…
Effective magnetic field induced by inhomogeneous Fermi velocity in strained honeycomb structures
M. Oliva-Leyva, J. E. Barrios-Vargas, G. Gonzalez de la Cruz
In addition to the known pseudomagnetic field, nonuniform strains independently induce a position-dependent Fermi velocity (PDFV) in graphene. Here we demonstrate that, due to the…
Electrical and thermal transport in coplanar polycrystalline graphene-hBN heterostructures
J. E. Barrios Vargas, B. Mortazavi, A. W. Cummings +5
We present a theoretical study of electronic and thermal transport in polycrystalline heterostructures combining graphene (G) and hexagonal boron nitride (hBN) grains of varying si…
Localized electronic states at grain boundaries on the surface of graphene and graphite
Adina Luican-Mayer, Jose E. Barrios-Vargas, Jesper Toft Falkenberg +8
Recent advances in large-scale synthesis of graphene and other 2D materials have underscored the importance of local defects such as dislocations and grain boundaries (GBs), and es…
Quantum Transport in Graphene in Presence of Strain-Induced Pseudo-Landau Levels
Mikkel Settnes, Nicolas Leconte, Jose E. Barrios-Vargas +2
We report on mesoscopic transport fingerprints in disordered graphene caused by strain-field induced pseudomagnetic Landau levels (pLLs). Efficient numerical real space calculation…
Near-field photocurrent nanoscopy on bare and encapsulated graphene
Achim Woessner, Pablo Alonso-González, Mark B. Lundeberg +14
Opto-electronic devices utilizing graphene have already demonstrated unique capabilities, which are much more difficult to realize with conventional technologies. However, the requ…
Electron localization in disordered graphene: multifractal properties of the wavefunctions
J. E. Barrios-Vargas, Gerardo G. Naumis
An analysis of the electron localization properties in doped graphene is performed by doing a numerical multifractal analysis. By obtaining the singularity spectrum of a tight-bind…
Critical wave functions in disordered graphene
J. E. Barrios-Vargas, Gerardo G. Naumis
In order to elucidate the presence of non-localized states in doped graphene, an scaling analysis of the wave function moments known as inverse participation ratios is performed. T…
Electrical conductivity and resonant states of doped graphene considering next-nearest neighbor interaction
J. E. Barrios-Vargas, Gerardo G Naumis
The next-nearest neighbor interaction (NNN) is included in a tight-binding calculation of the electronic spectrum and conductivity of doped graphene. As a result, we observe a wide…
