General Lab Information

The stacker is a robotic motion system that precisely handles stamp-supported flakes and substrates for the stacking procedure to fabricate heterostructures. A hexapod provides six-degrees-of-freedom control of the stamp motion, enabling arbitrarily complex motion in the approach, pressing, and detachment steps. The substrate motion stage can drive to flakes of interest, and can rotate in order to fabricate layered moiré heterostructures. Integrated heaters and a cooling loop regulate the stamp/sample temperature.

Status: The stacker is currently being commissioned; it is available for science-commissioning projects.
