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…
Slide and Twist: Manipulating Polarization in Multilayer Hexagonal Boron-Nitride
Sanber Vizcaya, Felipe Perez Riffo, Juan M. Florez +1
This study explores the world of across-layer sliding ferroelectricity in multilayer hexagonal boron nitride (hBN) and gallium nitride (hGaN), aiming to control out-of-plane polari…
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…
