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…
Radiation-induced dynamical formation of Floquet-Bloch bands in Dirac Hamiltonians
Yuriko Baba, Vanessa Junk, Wolfgang Hogger +3
Recent experiments, combing ultrafast strong-field irradiation of surfaces with time- and angle-resolved photoemission spectroscopy, allow for monitoring the time-dependent charge…
Superballistic conduction in hydrodynamic antidot graphene superlattices
Jorge Estrada-Álvarez, Juan Salvador-Sánchez, Ana Pérez-Rodríguez +9
Viscous electron flow exhibits exotic signatures such as superballistic conduction. In order to observe hydrodynamics effects, a 2D device where the current flow is as inhomogeneou…
Impact of vacancies on twisted bilayer graphene quantum point contacts
Pablo Moles, Francisco Domínguez-Adame, Leonor Chico
We carry out an extensive numerical study of low-temperature electronic transport in quantum point contacts based on twisted bilayer graphene. Assuming ballistic electron dynamics,…
Alternative routes to electron hydrodynamics
Jorge Estrada-Álvarez, Francisco Domínguez-Adame, Elena Díaz
Viscous flow of interacting electrons in two dimensional materials features a bunch of exotic effects. A model resembling the Navier-Stokes equation for classical fluids accounts f…
Effect of the external fields in high Chern number quantum anomalous Hall insulators
Yuriko Baba, Mario Amado, Enrique Diez +2
A quantum anomalous Hall state with high Chern number has so far been realized in multiplayer structures consisting of alternating magnetic and undoped topological insulator layers…
Generation and control of non-local chiral currents in graphene superlattices by orbital Hall effect
Juan Salvador-Sánchez, Luis M. Canonico, Ana Pérez-Rodríguez +15
Graphene-based superlattices offer a new materials playground to exploit and control a higher number of electronic degrees of freedom, such as charge, spin, or valley for disruptiv…
Impact of electron-electron interactions on the thermoelectric efficiency of graphene quantum point contacts
Irián Sánchez-Ramírez, Yuriko Baba, Leonor Chico +1
Thermoelectric materials open a way to harness dissipated energy and make electronic devices less energy-demanding. Heat-to-electricity conversion requires materials with a strongl…
Quantum nanoconstrictions fabricated by cryo-etching in encapsulated graphene
Vito Clericò, Juan Antonio Delgado-Notario, Marta Saiz-Bretín +7
More than a decade after the discovery of graphene, ballistic transport in nanostructures based on this intriguing material still represents a challenging field of research in two-…
Floquet engineering of Dirac cones on the surface of a topological insulator
A. Diaz-Fernandez, E. Diaz, Álvaro Gómez-León +2
We propose to Floquet-engineer Dirac cones at the surface of a three-dimensional topological insulator. We show that a large tunability of the Fermi velocity can be achieved as a f…
Electric control of the bandgap in quantum wells with band-inverted junctions
A. Diaz-Fernandez, Leonor Chico, F. Dominguez-Adame
In IV-VI semiconductor heterojunctions with band-inversion, such as those made of PbSnTe or PbSnSe, interface states are properly described by a two-ban…
Tuning the Fermi velocity in Dirac materials with an electric field
A. Diaz-Fernandez, L. Chico, J. W. Gonzalez +1
Dirac materials are characterized by energy-momentum relations that resemble those of relativistic massless particles. Commonly denominated Dirac cones, these dispersion relations…
