Magneto transport in bilayer graphene cavities — •Florian Schöppl, Michael Barth, Klaus Richter, and Angelika Knothe — Institut für Theoretische Physik, 93053 Regensburg, Germany

The remarkable sample quality of bilayer graphene in combination with the unprecedented electronic control of the band-structure makes bilayer graphene an excellent platform for electron optics. While the purity of the system allows for ballistic transport on the micrometer scales [1,2], the trigonal warping of the band structure close to each K points induces a valley dependent selection of momenta leading to unique transport and scattering properties [3,4]. Interested in the interplay of symmetry breaking induced by a variety of all-electronic gate confinements and the trigonal warping, we implement various quantum mechanical tight binding models and deploy them to investigate magneto transport through bilayer graphene cavities.
