Suppression of decoherence in a graphene monolayer ring
arXiv:1407.8358 · doi:10.1063/1.4894471
Abstract
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 harmonics appear. This phenomenon is attributed to an increase of the phase coherence length due to reduction of spin flip scattering.
