title: Room-Temperature Quantum Transport Signatures in Graphene/LaAlO3/SrTiO3Heterostructures.
abstract: High mobility graphene field-effect devices, fabricated on the complex-oxide heterostructure LaAlO3/SrTiO3, exhibit quantum interference signatures up to room temperature. The oxide material is believed to play a critical role in suppressing short-range and phonon contributions to scattering. The ability to maintain pseudospin coherence at room temperature holds promise for the realization of new classical and quantum information technologies.
