Observation of Even Denominator Fractional Quantum Hall Effect in Suspended Bilayer Graphene
Observation of Even Denominator Fractional Quantum Hall Effect in Suspended Bilayer Graphene
We investigate low-temperature magneto-transport in recently developed, high-quality multi-terminal suspended bilayer graphene devices, enabling the independent measurement of the longitudinal and transverse resistance. We observe clear signatures of the fractional quantum Hall effect, with different states that are either fully developed, and exhibit a clear plateau in the transverse resistance …
