| Freie Schlagworte | frequency and current independent quantum Hall resistance ; primary standard of impedance |
| Zusammenfassung | The quantum Hall resistance at frequencies in the kHz range shows frequency- and current-dependent deviations from the quantized dc resistance value. These effects have been attributed to a superposition of the ac longitudinal resistance. Nulling this superposition results in a frequency- and current independent quantum Hall resistance and allows the application as a primary standard of impedance. |
