Facilities
We have a state-of-the-art lab facility in the Physical Sciences Building (PSC) for measurement and air-free van der Waals assembly and nanofabrication. A second lab in John S. Toll Physics Building supports single-crystal synthesis efforts, which requires chemical handling facilities prohibited in PSC. Renovations are now mostly complete (awaiting an electrical upgrade in Toll lab), and we are in process of constructing and installing equipment.
Measurement
Leiden Dilution Refrigerator
Temperature: 37 mK - 4 K
Magnet: 10 T Solenoid (spec)
With top-loading sample probe
Sample in high vacuum.
We are slowly returning this dil fridge back into operations.
Janis Cryostat
Temperature: 3 K - 300 K
Magnet: None
Sample in high vacuum.
We are re-fitting this cryostat with new sample mount. This simple cryostat is ideal for rapid measurements to support device fabrication pathfinding.
BlueFors LD250 Dry Dil Fridge
To arrive Summer 2026
Temperature: 20 mK - 4 K (spec)
Magnet: 14 T Solenoid
With bottom-loading probe.
Sample in high vacuum.
Oxford TeslatronPT VTI
To arrive Summer 2026
Temperature: 1.5 K - 300 K
Magnet: 14 T Solenoid
With top-loading probe.
Sample in Helium vapor.
In addition to the equipment above, we also use various shared instruments at the University of Maryland:
Nanofabrication: FabLab.
Transport/magnetic measurement: Quantum Materials Center.
Structural characterization: Quantum Materials Center and X-ray Crystallographic Center.
Surface and nanoscale imaging: Surface Analysis Center and AimLab.
Specialized crystal synthesis: Quantum Materials Center.
Machine shop service: Terrapin Works IFL
