Valley filtering by a line-defect in graphene: quantum interference and inversion of the filter effect
Lucas H. Ingaramo, Luis E. F. Foa Torres
Valley filters are crucial to any device exploiting the valley degree of freedom. By using an atomistic model, we analyze the mechanism leading to the valley filtering produced by…
Floquet bound states around defects and adatoms in graphene
D. A. Lovey, Gonzalo Usaj, L. E. F. Foa Torres +1
Recent studies have focused on laser-induced gaps in graphene which have been shown to have a topological origin, thereby hosting robust states at the sample edges. While the focus…
Crafting zero-bias one-way transport of charge and spin
L. E. F. Foa Torres, V. Dal Lago, E. Suárez Morell
We explore the electronic structure and transport properties of a metal on top of a (weakly coupled) two-dimensional topological insulator. Unlike the widely studied junctions betw…
