Gate-tunable Veselago interference in a bipolar graphene microcavity
Charge carriers in graphene can be manipulated, e.g., collimated or focused, as in conventional optics but the efficiency of these processes remains low. Zhang et al. demonstrate interference of electrons in a novel graphene microcavity device and use it to enhance collimation efficiency of the elec...
