    Correlated phenomena in graphene at high and low carrier density
    (2021) Geurs, Johannes; Smet, Jurgen H. (Dr.)
    This dissertation studies electronic transport in graphene at high and low carrier density. At very high carrier densities, the band structure of graphene features a Van Hove singularity. Magnetotransport measurements suggest that below 110K, a pseudogap opens in graphene, combined with a Lifshitz transition. At low carrier density, it is possible to treat the electron liquid in graphene by electron hydrodynamics. A graphene Tesla valve is presented, a device that works as an electron viscometer.
