Problem
This solves problems of ohm dissemination and reduces the chain of calibration. Limit: device sizes of 1 cm.
Invention
This invention utilizes the unique properties of graphene to build p-n junctions working in the quantum Hall regime that allow convenient resistance scaling. This device would provide more than one value of resistance traceable to the quantum Hall effect. A graphene device capable of achieving many values of quantized resistances.
Potential Commercial Applications
Invention would offer different values of resistances with similar precision as the currently existing available standards.
Competitive Advantage
This option reduces the need for bulky equipment and, by simplifying the calibration chain, can improve resistance uncertainties.
