Generalized Hamiltonian for Kekulé graphene and the emergence of valley-cooperative Klein tunneling
Santiago Galván y García, Thomas Stegmann, Yonatan Betancur-Ocampo
We introduce a generalized Hamiltonian describing not only all topological phases observed experimentally in Kekulé graphene (KekGr) but predicting also new ones. These phases show…
Valley-dependent time evolution of coherent electron states in tilted anisotropic Dirac materials
Yonatan Betancur-Ocampo, Erik Díaz-Bautista, Thomas Stegmann
The effect of the Dirac cone tilt of anisotropic two-dimensional materials on the time evolution of coherent electron states in the presence of electric and magnetic fields is stud…
Steering the current flow in twisted bilayer graphene
Jesús Arturo Sánchez-Sánchez, Montserrat Navarro-Espino, Yonatan Betancur-Ocampo +2
A nanoelectronic device made of twisted bilayer graphene (TBLG) is proposed to steer the direction of the current flow. The ballistic electron current, injected at one edge of the…
