High mobility graphene field-effect devices, fabricated on the complex-oxide heterostructure LaAlO /SrTiO , 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.
在 LaAlO/SrTiO 复杂氧化物异质结构上制造的高迁移率石墨烯场效应器件在室温下表现出量子干涉特征。氧化物材料被认为在抑制短程和声子散射方面起着关键作用。在室温下保持赝自旋相干的能力有望实现新的经典和量子信息技术。
