## Description

- description: Electronic quality of graphene has improved significantly over the
    past two decades, revealing novel exotic phenomena. However, even state-of-the-art
    devices exhibit substantial spatial charge fluctuations originating from charged
    defects inside encapsulating crystals, which limits their performance. Here, we
    overcome this issue by assembling devices where graphene is encapsulated with
    the other graphene layers while remaining electronically decoupled from them via
    large twist angle. Doping of the encapsulating graphene layer, introduces strong
    Coulomb screening which is maximised by the sub-nanometer distance between the
    layers, and reduces inhomogeneity at the neutrality point of the next layer down
    to a few carriers per macroscopic area of the device. As a result, our devices
    show Landau quantization at magnetic fields of 3-5 milli-Tesla, while quantum
    and transport mobilities exceeding 3x106 cm2V-1s-1 and (30-40)x106 cm2V-1s-1 correspondently.
    Our novel encapsulation approach can be applied to other two-dimensional systems,
    enabling further exploration of electronic properties in ultra-pure devices.
