Robotic material stacking machine: Rapid fabrication of moiré heterostructures

Presenter: Zachariah Hennighausen

Hennighausen and his colleagues have constructed a robotic material stacking machine that is able to stack nearly any nanomaterial into a complex configuration with surprising speed (e.g., 10-layer twisted graphene heterostructure in 2.5 minutes). Further, they are able to stack wafer-scale grown materials and are not limited to only exfoliated materials, thereby moving the technology closer to industry application. The team is aiming to use the stacking machine to rapidly fabricate prototypes of promising nanomaterial technology, and collaborate with other groups for characterization.
