## Description

- description: Interfaces of van der Waals (vdW) materials such as graphite and hexagonal
    boron nitride (hBN) exhibit low-friction sliding due to their atomically-Jat surfaces
    and weak vdW bonding. We demonstrate that microfabricated gold also slides with
    low friction on hBN. This enables the arbitrary post-fabrication repositioning
    of device features both at ambient conditions as well as in-situ to a measurement
    cryostat. We demonstrate mechanically-reconfigurable vdW devices where device
    geometry and position are continuously-tunable parameters. By fabricating slidable
    top gates on a graphene-hBN device, we produce a mechanically-tunable quantum
    point contact where electron con?nement and edge-state coupling can be continuously
    modified. Moreover, we combine in-situ sliding with simultaneous electronic measurements
    to create new types of scanning probe experiments, where gate electrodes and even
    entire vdW heterostructures devices can be spatially scanned by sliding across
    a target.
