Robust operation of a GaAs tunable barrier electron pump
S. P. Giblin, M. -H. Bae, N. Kim +2
We demonstrate the robust operation of a gallium arsenide tunable-barrier single-electron pump operating with 1 part-per-million accuracy at a temperature of ~K and a pumping…
Re-evaluation of uncertainty for calibration of M and G resistors at NPL
Stephen P. Giblin
The uncertainty for calibrating M and G resistors using the NPL high-resistance CCC bridge has been re-evaluated, resulting in combined uncertainties of …
Exploring a new ammeter traceability route for ionisation chamber measurements
Stephen P. Giblin, Giuseppe Lorusso
We compared the performance of a commercial ammeter and a home-made integrating electrometer in reading ionisation chamber currents less than 100 pA. The integrating electrometer c…
Validation of the ultrastable low-noise current amplifier as travelling standard for small direct currents
Dietmar Drung, Christian Krause, Stephen P. Giblin +7
An interlaboratory comparison of small-current generation and measurement capability is presented with the ultrastable low-noise current amplifier (ULCA) acting as travelling stand…
Stabilization of single-electron pumps by high magnetic fields
J. D. Fletcher, M. Kataoka, S. P. Giblin +8
We study the effect of perpendicular magnetic fields on a single-electron system with a strongly time-dependent electrostatic potential. Continuous improvements to the current quan…
Single- and few-electron dynamic quantum dots in a perpendicular magnetic field
S. J. Wright, A. L. Thorn, M. D. Blumenthal +9
We present experimental studies of the current pumped through a dynamic quantum dot over a wide range of magnetic fields. At low fields we observe repeatable structure indicating i…
