Symmetry selection rule for the band-edge shift current in two dimensions
Felipe Pérez Riffo, Matías Castro, Leonor Chico +2
The shift current is the intrinsic bulk photovoltaic response of a crystal without an inversion center. In graphene multilayers, calculations report large band-edge shift currents…
Tuning magnetism in graphene nanoribbons via strain and adatoms
Pablo Moles, Hernán Santos, Francisco Domínguez-Adame +1
We investigate the impact of strain and adsorbed H adatoms on the magnetic properties of zigzag graphene nanoribbons (ZGNRs) using a combination of tight-binding and density functi…
Controlling the layer localization of gapless states in bilayer graphene with a gate voltage
W. Jaskólski, M. Pelc, Garnett W. Bryant +2
Experiments in gated bilayer graphene with stacking domain walls present topological gapless states protected by no-valley mixing. Here we research these states under gate voltages…
Topologically confined states at corrugations of gated bilayer graphene
M. Pelc, W. Jaskólski, A. Ayuela +1
We investigate the electronic and transport properties of gated bilayer graphene with one corrugated layer, which results in a stacking AB/BA boundary. When a gate voltage is appli…
Electronic conductance of twisted bilayer nanoribbon flakes
M. Pelc, E. Suárez Morell, L. Brey +1
We study the transport properties of a twisted bilayer graphene flake contacted by two monolayer nanoribbons which act as leads. We analyze the conductance in terms of the spectra…
Van der Waals interaction in magnetic bilayer graphene nanoribbons
H. Santos, A. Ayuela, L. Chico +1
We study the interaction energy between two graphene nanoribbons by first principles calculations, including van der Waals interactions and spin polarization. For ultranarrow zigza…
Charge redistribution and interlayer coupling in twisted bilayer graphene under electric fields
E. Suárez Morell, P. Vargas, L. Chico +1
We investigate the electronic density redistribution of rotated bilayer graphene under a perpendicular electric field, showing that the layers are actually coupled even for large a…
Edge states and flat bands in graphene nanoribbons with arbitrary geometries
W. Jaskolski, A. Ayuela, M. Pelc +2
We prescribe general rules to predict the existence of edge states and zero-energy flat bands in graphene nanoribbons and graphene edges of arbitrary shape. No calculations are nee…
Gate-controlled conductance through bilayer graphene ribbons
J. W. González, H. Santos, E. Prada +2
We study the conductance of a biased bilayer graphene flake with monolayer nanoribbon contacts. We find that the transmission through the bilayer ribbon strongly depends on the app…
Electronic transport through bilayer graphene flakes
J. W. Gonzalez, H. Santos, M. Pacheco +2
We investigate the electronic transport properties of a bilayer graphene flake contacted by two monolayer nanoribbons. Such a finite-size bilayer flake can be built by overlapping…
Carbon nanoelectronics: unzipping tubes into graphene ribbons
H. Santos, L. Chico, L. Brey
We report on the transport properties of novel carbon nanostructures made of partially unzipped carbon nanotubes, which can be regarded as a seamless junction of a tube and a nanor…
