Graphene Nanobubbles as Valley Filters and Beamsplitters
Mikkel Settnes, Stephen R. Power, Mads Brandbyge +1
The low energy band structure of graphene has two inequivalent valleys at K and K' points of the Brillouin zone. The possibility to manipulate this valley degree of freedom defines…
Quantum Transport in Graphene in Presence of Strain-Induced Pseudo-Landau Levels
Mikkel Settnes, Nicolas Leconte, Jose E. Barrios-Vargas +2
We report on mesoscopic transport fingerprints in disordered graphene caused by strain-field induced pseudomagnetic Landau levels (pLLs). Efficient numerical real space calculation…
Electron interference in ballistic graphene nanoconstrictions
Jens Baringhaus, Mikkel Settnes, Johannes Aprojanz +3
We have realized nanometer size constrictions in ballistic graphene nanoribbons grown on sidewalls of SiC mesa structures. The high quality of our devices allows the observation of…
