Quantum phenomena arise in solids when electrons interact over periodic potentials defined by an underlying crystalline lattice. In 2-dimensional materials, weak chemical bonds between neighboring atoms allow the crystal to be easily cleaved, and deterministically re-assembled into new lattice structures which cannot be synthesized using traditional methods. Electrons are sensitive to the potential imposed by both lattices that comprise the interface, giving rise to new quantum phenomena foreign to each parent material.
Our group brings this paradigm to new, air-sensitive 2D materials by combining single crystal synthesis with new layer-by-layer assembly and nanoscale device fabrication techniques under cryogenic temperatures and inert environments. We search for signatures of exotic electronic phenomena at our interfaces with transport measurements at ultra-low temperatures and extreme magnetic fields, where quantum physics dominates. Finally, we seek to connect new quantum phenomena with applications in emerging technologies.
