Researchers from Finland's MIKES center and Aalto University demonstrated that quantum hall resistance measurement using graphene on silicon carbide can be done at lower magnetic fields and on industrially produced material.
The researchers say that it is well known that graphene is excellent for quantum hall resistance measurement. In fact, it outperforms the currently used gallium arsenide in many aspects. These measurements were performed on industrially produced material supplied by Graphensic that applies a high growth temperature method to produce the graphene. Photolithographic patterning and electrical contacts were made by Aalto University.
