High-accuracy graphene quantum Hall array resistance standards based on wye-delta transformation
Nature ·
The Brief
- The article describes high-accuracy resistance standards based on graphene quantum Hall arrays.
- The standards are based on a wye-delta transformation approach, according to the title.
Why it matters
Quantum Hall resistance standards provide reference values for precise electrical resistance measurement, so improvements in their accuracy matter to metrology laboratories.
