Development of a Four-channel System for Johnson Noise Thermometry

June 13, 2010
Author(s)
Alessio Pollarolo, Jifeng Qu, Horst Rogalla, Paul Dresselhaus, Samuel Benz
Long integration time is necessary to reach low uncertainty when measuring temperature through Johnson Noise Thermometry (JNT). The main goal of the NIST JNT experiment is to achieve a 6 10-6 relative uncertainty in the measurement of the water triple

Microwave Optimization of 10 V PJVS Circuits

June 13, 2010
Author(s)
Paul D. Dresselhaus, Mike Elsbury, Charles J. Burroughs, Samuel P. Benz
Proper operation of programmable Josephson voltage standard arrays depends on the uniform distribution of microwaves to a large number of Josephson junctions. Too much or too little microwave power will change the current range of a junction s constant

Digital Circuits Using Self-Shunted Nb/NbxSi1-x/Nb Josephson Junctions

May 27, 2010
Author(s)
David I. Olaya, Paul Dresselhaus, Samuel Benz, Anna Herr, Quentin Herr, alex Ioannidis, Donald Miller, Alan Kleinsasser
For the first time superconducting digital circuits based on novel Josephson junctions with amorphous niobium-silicon (a-NbSi) barriers were designed, fabricated and tested. Compared with the resistively shunted aluminum-oxide-barrier junctions that are

Niobium-silicide junction technology for superconducting digital electronics

April 1, 2010
Author(s)
David I. Olaya, Paul D. Dresselhaus, Samuel P. Benz
We present a technology based on Nb/NbxSi1-x/Nb junctions, with barriers near the metal-insulator transition, for applications in superconducting electronics (SCE) as an alternative to Nb/AlOx/Nb tunnel junctions. Josephson junctions with co-sputtered

Niobium-silicide Junction technology for superconducting digital electronics

June 15, 2009
Author(s)
David I. Olaya, Paul D. Dresselhaus, Samuel P. Benz
Digital superconducting electronics (SCE), which allows for very low power consumption and fast switching speeds, are a promising technology to deliver ultra-high performance computation. Currently, the preferred technology for junctions in SCE consists of

Integrated Broadband Lumped-Element Symmetrical-Hybrid N-way Power Dividers

June 7, 2009
Author(s)
Mike Elsbury, Paul D. Dresselhaus, Samuel P. Benz, Zoya Popovic
This paper presents a monolithically-integrated, broadband, lumped-element, symmetrical-hybrid power divider centered at 20 GHz which was designed and fabricated to uniformly distribute power to arrays of Josephson junctions for superconducting voltage

1V and 10V SNS Programmable Voltage Standards for 70 GHz

June 3, 2009
Author(s)
Franz Mueller, Ralf Behr, T. Weimann, Luis Palafox, David I. Olaya, Paul Dresselhaus, Samuel Benz
Programmable Josephson voltage standards (PJVSs) in combination with fast switchable DC current sources have opened up new applications in the field of low frequency AC metrology. The growing interest in output voltages of up to 10 V initiated efforts by

Amorphous Nb-Si Barrier Junctions for Voltage Standard and Digital Applications

June 3, 2009
Author(s)
David I. Olaya, Paul Dresselhaus, Samuel Benz, Jon E. Bjarnason, Erich N. Grossman
Amorphous Nb-Si has been previously demonstrated as a Josephson junction barrier material for Nb-based superconducting voltage standard circuits, including both dc programmable and ac Josephson voltage standards operating at frequencies up to 20 GHz. This
