New tools for probing 2D quantum materials

Two dimensional materials made by van der Waals assembly offer a unique way of exploring novel materials properties. The fact that electrons are primarily confined to atomically thin crystal planes grants functionalities distinct from bulk materials—proximate layers and localized probes can interface with the entire electron system rather than just the surface. In this talk, I will discuss new homebuilt scanning probes and measurement systems tailored to probe emergent behavior in graphene-based materials. With these tools we can probe electron hydrodynamics and moiré superlattice electron transport in monolayer graphene. There is also promise for elucidating interactions in emergent superconductivity in magic angle twisted bilayer graphene.
