我们报道了一种将载流子限制在单层石墨烯中的方法，这种方法导致了具有场诱导量子限制的量子器件。我们证明了库仑阻塞效应在垂直于石墨烯器件的均匀磁场下演化。我们的实验结果表明，在石墨烯中实现了场诱导量子点，并通过磁场实现了量子限制-解限制的转变。
We report an approach to confine the carriers in single-layer graphene, which leads to quantum devices with field-induced quantum confinement. We demonstrated that the Coulomb-blockade effect evolves under a uniform magnetic field perpendicular to the graphene device. Our experimental results show that field-induced quantum dots are realized in graphene, and a quantum confinement-deconfinement transition is switched by the magnetic field.
