Journal ArticleDOI
Nb/al/alox/alox/al/nb josephson junctions for programmable voltage standards
TL;DR: In this article, the microwave characteristics of Josephson junctions based on a superconductor-insulator-normal insulator-superconductor sandwich, fabricated in Nb/Al/AlOx technology, were studied.
Journal ArticleDOI
Development and metrological applications of Josephson arrays at PTB
TL;DR: In this paper, the principal contributions from PTB to the present state of Josephson voltage standards with particular focus on developments and applications for ac standards in metrology and their proof-of-concept demonstrations are summarized.
Journal ArticleDOI
Design and fabrication of 10 V SINIS Josephson arrays for programmable voltage standards
TL;DR: In this paper, the fabrication and the chip layout of 69120 SINIS Josephson junction series arrays for a programmable 10 V Josephson dc voltage standard are presented under 70 GHz microwave irradiation, the currentvoltage characteristic exhibits a non-hysteretic voltage step with a step width of 200 µA.
Journal ArticleDOI
The simulation and measurement of the response of Josephson junctions to optoelectronically generated short pulses
Jonathan M. Williams,Tjbm Janssen,Luis Palafox,D.A. Humphreys,Ralf Behr,Johannes Kohlmann,F. Muller +6 more
TL;DR: In this article, a method of driving series arrays of non-hysteretic Josephson junctions using optoelectronically generated pulses to synthesize a variable output voltage is described.
Journal ArticleDOI
NbSi Barrier Junctions Tuned for Metrological Applications up to 70 GHz: 20 V Arrays for Programmable Josephson Voltage Standards
TL;DR: In this paper, the authors demonstrate how Nb-doping of the amorphous Si barrier causes the transition from an underdamped to a desired overdamped junction behavior, and demonstrate the performance of 20 V circuits with nearly 140 000 double-stacked Josephson junctions.
