Conception of an enhanced mechanism for a new Kibble balance directly traceable to the quantum SI
Lorenz Keck, Frank Seifert, David Newell +3
The ``Quantum Electro-Mechanical Metrology Suite'' (QEMMS) is being designed and built at the National Institute of Standards and Technology. It includes a Kibble balance, a Graphe…
Fabrication of uniformly doped graphene quantum Hall arrays with multiple quantized resistance outputs
Swapnil M. Mhatre, Ngoc Thanh Mai Tran, Heather M. Hill +7
In this work, limiting factors for developing metrologically useful arrays from epitaxial graphene on SiC are lifted with a combination of centimeter-scale, high-quality material g…
Design of electrostatic feedback for an experiment to measure
Stephan Schlamminger, Leon Chao, Vincent Lee +2
The torsion pendulum at the heart of the apparatus to measure the gravitational constant, at the Bureau International des Poids et Mesures (BIPM) is used to measure the gravita…
Chromium-Doped Bismuth Antimony Telluride for Future Quantum Hall Resistance Standards
Albert F. Rigosi Linsey K. Rodenbach, Alireza R. Panna, Shamith U. Payagala +10
Since 2017, epitaxial graphene has been the base material for the US national standard for resistance. A future avenue of research within electrical metrology is to remove the need…
Spectroscopic assessment of short-term nitric acid doping of epitaxial graphene
Ngoc Thanh Mai Tran, Swapnil M. Mhatre, Cristiane N. Santos +10
This work reports information on the transience of hole doping in epitaxial graphene devices when nitric acid is used as an adsorbent. Under vacuum conditions, desorption processes…
Timescales for Nitric Acid Desorption in Epitaxial Graphene Devices
Swapnil M. Mhatre, Ngoc Thanh Mai Tran, Heather M. Hill +6
This work reports the dynamics of transient hole doping in epitaxial graphene devices by using nitric acid as an adsorbent. The timescales associated with corresponding desorption…
