Quantum mechanical current-to-voltage conversion with quantum Hall resistance array
Dong-Hun Chae, Mun-Seog Kim, Wan-Seop Kim +2
Accurate measurement of the electric current requires a stable and calculable resistor for an ideal current to voltage conversion. However, the temporal resistance drift of a physi…
Simple digital phase-measuring algorithm for low-noise heterodyne interferometry
Wataru Kokuyama, Hideaki Nozato, Akihiro Ohta +1
We present a digital algorithm for measuring the phase difference between two sinusoidal signals that combines the modified fringe-counting method with two-sample zero crossing to…
Improved measurement results for the Avogadro constant using a 28Si-enriched crystal
Y Azuma, P Barat, G Bartl +26
New results are reported from an ongoing international research effort to accurately determine the Avogadro constant by counting the atoms in an isotopically enriched silicon cryst…
Precision measurements of the Planck and Avogadro constants
Horst Bettin, Kenichi Fujii, John Man +3
Precision measurements of the fundamental constants are tour de force of basic metrology, where the useful information is usually beyond the last digit of the measured value. They…
