Electron counting capacitance standard and quantum metrology triangle experiments at PTB
H Scherer, J Schurr, F J Ahlers
This paper summarizes the final results of the electron counting capacitance standard experiment at the Physikalisch-Technische Bundesanstalt (PTB) achieved since the publication o…
Nonequilibrium mesoscopic conductance fluctuations as the origin of 1/f noise in epitaxial graphene
Cay-Christian Kalmbach, Franz Josef Ahlers, Jürgen Schurr +6
We investigate the 1/f noise properties of epitaxial graphene devices at low temperatures as a function of temperature, current and magnetic flux density. At low currents, an expon…
Reflections on a Measurement of the Gravitational Constant Using a Beam Balance and 13 Tons of Mercury
S. Schlamminger, R. E. Pixley, F. Nolting +2
In 2006, a final result of a measurement of the gravitational constant performed by researchers at the University of Zürich was published. A value of $G=6.674\,252(122)\times 1…
Towards a Graphene-Based Quantum Impedance Standard
C. -C. Kalmbach, J. Schurr, F. J. Ahlers +4
Precision measurements of the quantum Hall resistance with alternating current (ac) in the kHz range were performed on epitaxial graphene in order to assess its suitability as a qu…
A Measurement of Newton's Gravitational Constant
St. Schlamminger, E. Holzschuh, W. Kündig +4
A precision measurement of the gravitational constant has been made using a beam balance. Special attention has been given to determining the calibration, the effect of a possi…
