## Description

- description: Quantum Hall effect (QHE) has been the ground to construct modern conceptual
    electronic systems with emerging physics including topo- logical superconductor
    and quantum information processing. It is known that the QHE is often much influenced
    by the interplay between the host two dimensional electron gases and the substrate,
    sometimes predicted to exhibit exotic topological states such as quantum anoma-
    lous Hall. Yet the understanding of the underlying physics and controllable engineering
    of this paradigm of interaction remain challenging. Here we demonstrate the observation
    of a distinct QHE, which differs markedly from the known picture, in graphene
    samples in contact with an anti- ferromagnetic insulator CrOCl. Owing to the interfacial
    charge transfer, Landau levels in monolayer graphene remain intact at negative
    filling fractions, but largely distorted from the original fan-like pattern at
    a positive total electron doping. In this regime of doping, the consequential
    Landau quantization follows a parabolic relation between the displacement field
    D and the magnetic field B, with the QHE phase reaching the limit of zero magnetic
    field, and prevails up to 100 K in a wide doping range from 0 to 10^13 cm−2. This
    robust QHE phase opens up new routes for manipulating the quantum electronic states,
    which may find applications in such as quantum meteorology as well as topological
    superconductivity.
