Measurements International (MI) Announces a Joint Research Collaboration with The National Institute of Standards and Technology (NIST) to Develop a Commercial Graphene Based Quantum Hall System.
PRESCOTT, Ontario – Measurements International (MI) a metrology-based company focused on developing products for Electrical Metrology at the primary standards level today announced a joint research collaboration to explore graphene-based Quantum Hall device with the National Institute of Standards and Technology (NIST).
NIST will contribute its part of the collaboration in the study of graphene Quantum Hall resistors. Graphene has the goal to replace the current generation of standards fabricated from gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs). Graphene promises a practical device for measuring electrical resistance that is to be easier and less expensive to make, and less demanding to operate, than the current generation of standards fabricated from gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs).
Measurements International is contributing the commercial Quantum Hall system which will be modified to allow for dual sample mount probe. This is already available in the 6800B system and allows the mounting of both the gallium arsenide (GaAs) and the new graphene-based device.
The cryogenics of the system which is based on a reliquifier system which does not require the transfer or need for purchase of liquid helium, and instead uses helium gas in a reliquifier for a cost-effective solution. This is the only system commercially available of its kind. For more on the 6800 systems please visit http://mintl.com/products/6800b-qhr-turnkey-system-with-helium-re-liquefaction/
The system will also use Measurements International room temperature DCC Bridge the 6020Q. The bridge offers a cheaper, more cost-effective solution the Cryogenic Current Comparators without large sacrifice inaccuracy or uncertainty.

Company President Duane Brown:
“We are delighted to be chosen by NIST as its partner for this leading-edge research project. Measurements International has been offering the very best Commercial QHR System since 1999, and we believe this shows the Measurement Communities continued trust in MI products.”

A Cheaper, Easier Resistance Standard on a Chip
Researchers at the (NIST, Gaithersburg, Md.) and Carnegie Mellon University in Pittsburgh, Pa., have deposited a graphene film on silicon carbide to produce a quantized ohm-on-a-chip.
