Manifestation of the bulk phase transition in the edge energy spectrum in a two dimensional bilayer electron system
E. V. Deviatov, A. Wurtz, A. Lorke +5
We use a quasi-Corbino sample geometry with independent contacts to different edge states in the quantum Hall effect regime to investigate the edge energy spectrum of a bilayer ele…

Observation of two relaxation mechanisms in transport between spin split edge states at high imbalance
E. V. Deviatov, A. Wurtz, A. Lorke +4
Using a quasi-Corbino geometry to directly study electron transport between spin-split edge states, we find a pronounced hysteresis in the I-V curves, originating from slow relaxat…
