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…
Unveiling the Electronic Origin of Anomalous Contact Conductance in Twisted Bilayer Graphene
Kevin J. U. Vidarte, Caio Lewenkopf, F. Crasto de Lima +3
This study theoretically investigates the contact conductance in twisted bilayer graphene (TBG), providing a theoretical explanation for recent experimental observations from scann…
Stoner ferromagnetism in low-angle twisted bilayer graphene at three-quarters filling
Kevin J. U. Vidarte, Felipe Pérez Riffo, Eric Suárez Morell +1
We present a theoretical investigation of the magnetic properties exhibited by twisted bilayer graphene (TBG) systems with small twist angles, where the appearance of flat miniband…
Theory of magnetism in the van der Waals magnet CrI3
Rodrigo Jaeschke-Ubiergo, Eric Suarez Morell, Alvaro Sebastian Nunez
We study the microscopical origin of anisotropic ferromagnetism in the van der Waals magnet CrI3. We conclude that the nearest neighbors exchange is well described by the Heisenber…
