Graphene Waves, a company focused on providing high quality epitaxial graphene and devices based on epitaxial graphene, received a $106,500 Phase I SBIR grant from the National Institute of Standards and Technology (NIST). The award will enable Graphene Waves to develop a quantum Hall resistance (QHR) standard based on graphene that can be deployed for general electrical calibration in industries.
Current QHR standard is based on GaAs/AlGaAs heterostructure and requires expensive liquid helium to operate. The continuous increase in price and unstable supply chain of liquid helium limit the QHR standard to be only affordable by the top National Metrology Institutes. With the advanced technology for graphene and the liquid-helium-free cryocooler, a QHR standard based on graphene will be available for on-site electrical calibration in industries worldwide.
