Coupling in concentric double quantum rings

Mühle, A.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2007)

We designed a device consisting of two concentric quantum rings in a GaAsAlGaAs heterostructure. The outer ring is connected to leads while the inner ring is only capacitively coupled to the rest of the system. Measuring ...

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 ...
