Valley splitter and transverse valley focusing in twisted bilayer graphene
We study transport in twisted bilayer graphene and show that electrostatic barriers can act as valley splitters, where electrons from the K (K^{′}) valley are transmitted only to, e.g., the top (bottom) layer, leading to valley-layer locked currents. We show that such a valley splitter is obtained w...
