Improvements of the programmable quantum current generator for better traceability of electrical current measurements
Sophie Djordjevic, Ralf Behr, Dietmar Drung +2
A programmable quantum current generator based on the application of Ohm's law to quantum voltage and resistance standards has demonstrated a realization of the ampere from the ele…
Quantitative measurement of the thermal contact resistance between a glass microsphere and a plate
Joris Doumouro, Elodie Perros, Alix Dodu +6
Accurate measurements of the thermal resistance between micro-objects made of insulating materials are complex because of their small size, low conductivity, and the presence of va…
A resistance bridge based on a cryogenic current comparator achieving sub- measurement uncertainties
W. Poirier, D. Leprat, F. Schopfer
A new resistance bridge has been built at the Laboratoire national de métrologie et d'essais (LNE) to improve the ohm realization in the (SI) of units from…
Quantum resistance standard accuracy close to the zero-dissipation state
Félicien Schopfer, Wilfrid Poirier
We report on a comparison of four GaAs/AlGaAs-based quantum resistance standards using an original technique adapted from the well-known Wheatstone bridge. This work shows that the…
RK/100 and RK/200 Quantum Hall Array Resistance Standards
W. Poirier, A. Bounouh, K. Hayashi +4
It is theoretically possible to combine several Hall bars in arrays to define new quantum standards with perfectly quantized resistance values. We have thus, for the first time, de…
Tunneling in very small GaAs MESFET
W. Poirier, D. Mailly, M. Sanquer
We study the transport through gated GaAS:Si wires of 0.5 micrometer length in the insulating regime and observe transport via elastic tunneling at very low temperature. We describ…
