Landau Velocity for Collective Quantum Hall Breakdown in Bilayer Graphene
Landau Velocity for Collective Quantum Hall Breakdown in Bilayer Graphene
Breakdown of the quantum Hall effect (QHE) is commonly associated with an electric field approaching the inter-Landau-level (LL) Zener field, the ratio of the Landau gap and the cyclotron radius. Eluded in semiconducting heterostructures, in spite of extensive investigation, the intrinsic Zener limit is reported here using high-mobility bilayer graphene …
