Description
Moiré materials are defined by a delicate interplay of symmetry and nanoscale registry, yet the most important structural tuning parameters are often frozen once a heterostructure is assembled. I will present a "scanning van der Waals microscope" that creates a pristine nanoscale 2D-2D junction on a probe and rotates the interface in situ, enabling continuous twist control while measuring electrical transport across the junction. The method is aimed at two longstanding bottlenecks: reconfigurable control of moiré interfaces and momentum-selective tunnelling spectroscopy of electronic structure with moiré-relevant resolution. I will summarize initial results from graphene-based junctions and discuss near-term directions toward tunable moiré heterostructures for quantum simulation.
