Twisted trilayer graphene under the microscope

Stacking van der Waals layers provides new opportunities to design electronic band structure. The weak bonding between layers both enables the addition of a relative twist and allows for relaxation into distinct local stacking configurations. In this talk, I will describe joint imaging and transport studies of twisted trilayer graphene which reveal how these factors generate a rich interplay between structural and electronic degrees of freedom over a variety of length scales. I will discuss distinct limits of interlayer angles and how our results inform the broader phase diagram of quantum electronic phases in twisted moiré multilayers.
