Abstract
High mobility graphene field-effect devices, fabricated on the complex-oxide heterostructure LaAlO<sub>3</sub> /SrTiO<sub>3</sub> , 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.
