Columbia researchers observe tunable quantum behavior in bilayer graphene
Date:7/10/2014

ed for the first time that varying the applied electric field causes a phase transition, but the exact nature of these different phases remains an open question. "While theory expects that we can tune the ground state order, the complexity of the system makes it difficult to determine exactly which order is actually realized," says Physics Professor and co-author Philip Kim.

"This is where the next phase of our research is headed," says Dean. "The implications for this result could be far reaching," he adds, "While we do not yet see any evidence of non-abelian states, the fact that we are able to modify the nature of the fractional quantum Hall effect by electric fields is a really exciting first step."

While previous efforts have been able to demonstrate different aspects of the sample requirement, no other group has been able to bring this all together into a single device. Dean attributes this success to the unique collaborative environment fostered at Columbia University. "This is truly a remarkable environment," he says, adding, "The open exchange of ideas across several disciplines makes the environment at Columbia a fertile ground for doing great science." Device fabrication and initial testing was done at Columbia University. Measurement under large magnetic fields was then performed by the Columbia team with the aid of the National High Magnetic Field Laboratory user facility in Tallahassee, Florida. "We have established a fantastic relationship with the NHFML over many years," says Dean. "The support provided by the NHMFL personnel at both the technical and scientific level has been invaluable to our efforts."
