Graphene, a revolutionary material for metrology

Graphene, a revolutionary material for metrology and the International System of units - September 2015

A French team of researchers based at National Metrology and Testing Laboratory (LNE) and various laboratories at National Center for Scientific Research (CNRS) has found that graphene, which led to the 2010 Nobel Prize in Physics, can be used to realize a primary standard of electrical resistance based on the quantum Hall effect, which operates with state-of-the-art accuracy and in experimental conditions much more practical than that required by conventional semiconductors.
