Spin-resolved Quantum Interference in Graphene
Mark B. Lundeberg, Joshua A. Folk
The unusual electronic properties of single-layer graphene make it a promising material system for fundamental advances in physics, and an attractive platform for new device techno…
Electrical generation of pure spin currents in a two-dimensional electron gas
S. M. Frolov, A. Venkatesan, W. Yu +2
Pure spin currents are measured in micron-wide channels of GaAs two-dimensional electron gas (2DEG). Spins are injected and detected using quantum point contacts, which become spin…
Control and Detection of Singlet-Triplet Mixing in a Random Nuclear Field
F. H. L. Koppens, J. A. Folk, J. M. Elzerman +7
We observe mixing between two-electron singlet and triplet states in a double quantum dot, caused by interactions with nuclear spins in the host semiconductor. This mixing is suppr…
The Kondo Effect in the Presence of Magnetic Impurities
H. B. Heersche, Z. de Groot, J. A. Folk +5
We measure transport through gold grain quantum dots fabricated using electromigration, with magnetic impurities in the leads. A Kondo interaction is observed between dot and leads…
