## Description

- description: A unique attribute of atomically thin quantum materials is the in-situ
    tunability of their electronic band structure by externally controllable parameters
    like electrostatic doping, electric field, strain, electron interactions, and
    displacement or twisting of atomic layers. This unparalleled control of the electronic
    bands has led to the discovery of a plethora of exotic emergent phenomena. But
    despite its key role, there is currently no versatile method for mapping the local
    band structure in advanced 2D materials devices in which the active layer is commonly
    embedded in various insulating layers and metallic gates. Utilizing a scanning
    superconducting quantum interference device, we image the de Haas-van Alphen quantum
    oscillations in a model system, the Bernal-stacked trilayer graphene with dual
    gates, which displays multiple highly-tunable bands. By resolving thermodynamic
    quantum oscillations spanning over 100 Landau levels in low magnetic fields, we
    reconstruct the band structure and its controllable evolution with the displacement
    field with unprecedented precision and spatial resolution of 150 nm. Moreover,
    by developing Landau level interferometry, we reveal shear-strain-induced pseudomagnetic
    fields and map their spatial dependence. In contrast to artificially-induced large
    strain, which leads to pseudomagnetic fields of hundreds of Tesla, we detect naturally
    occurring pseudomagnetic fields as low as 1 mT corresponding to graphene twisting
    by just 1 millidegree over one µm distance, two orders of magnitude lower than
    the typical angle disorder in high-quality twisted bilayer graphene devices. This
    ability to resolve the local band structure and strain on the nanoscale opens
    the door to the characterization and utilization of tunable band engineering in
    practical van der Waals devices.
