“What new technology does is create new opportunities to do a job that customers want done,” according to Silicon Valley thinker and entrepreneur Tim O’Reilly.
One of the National Institute of Science and Technology’s foremost missions is the pursuit of solutions to complex scientific and technological problems in the crucial measurement field.
Hand in hand with this goal is the commitment to introduce the results of NIST research through the commercial marketplace so that NIST’s work will simultaneously benefit the American public and the American economy.
A freshly patented technology designed “to do a job that customers want done” is the Gateless P-N junction metrolog. This invention by NIST scientist Dr. Albert F. Rigosi solves the issue of using standard metal electrical contacts for connecting multiple devices composed of the same material.
The invention provides the process of building a special device for resistance metrology that allows a user to output many different quantum resistances, like a variable resistor.
Dr. Rigosi, of the Applied Electrical Metrology Group in the Quantum Measurement Division of NIST’s Physical Measurement Laboratory, began work on the project in 2017, and the patent (U. S. Patent 11474134) was issued in October 2022.
He explains, “Graphene is a material that is very good at conducting electricity and light, and it can be made in many ways. One of the most common ways is to grow it on silicon carbide. This type of graphene is called epitaxial graphene (EG). EG has many potential applications, such as making high-speed electronic devices and sensors.
“However, one of the challenges with EG is that it can be difficult to make devices with regions of varying charge carrier (like el ..
