Large tunable valley splitting in edge-free graphene quantum dots on boron nitride
Nils M. Freitag, Tobias Reisch, Larisa A. Chizhova +10
Coherent manipulation of binary degrees of freedom is at the heart of modern quantum technologies. Graphene offers two binary degrees: the electron spin and the valley. Efficient s…
Electrostatically confined monolayer graphene quantum dots with orbital and valley splittings
Nils M. Freitag, Larisa A. Chizhova, Peter Nemes-Incze +8
The electrostatic confinement of massless charge carriers is hampered by Klein tunneling. Circumventing this problem in graphene mainly relies on carving out nanostructures or appl…
Magneto-optical response of graphene: probing substrate interactions
L. A. Chizhova, J. Burgdörfer, F. Libisch
Magneto-optical transitions between Landau levels can provide precise spectroscopic information on the electronic structure and excitation spectra of graphene, enabling probes of s…
Graphene quantum dot on boron nitride: Dirac cone replica and Hofstadter butterfly
L. A. Chizhova, F. Libisch, J. Burgdörfer
Graphene flakes placed on hexagonal boron nitride feature in the presence of a magnetic field a complex electronic structure due to a hexagonal moiré potential resulting from the v…
