  • Aharonov-Bohm effect in an electron-hole graphene ring system 
    Smirnov, D.; Schmidt, H.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2012)
    Aharonov-Bohm oscillations are observed in a graphene quantum ring with a topgate covering one arm of the ring. As graphene is a gapless semiconductor, this geometry allows to study not only the quantum interference of ...
  • Quantum interference in an electron-hole graphene ring system 
    Smirnov, D.; Schmidt, H.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    Quantum interference is observed in a graphene ring system via the Aharonov Bohm effect. As graphene is a gapless semiconductor, this geometry allows to study the unique situation of quantum interference between electrons ...
  • Suppression of decoherence in a graphene monolayer ring 
    Smirnov, D.; Rode, J.C.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2014)
    The influence of high magnetic fields on coherent transport is investigated. A monolayer graphene quantum ring is fabricated and the Aharonov-Bohm effect is observed. For increased magnitude of the magnetic field, higher ...
