Journal ArticleDOI
Submicron gap capacitor for measurement of breakdown voltage in air
TL;DR: In this paper, the authors developed a new method for measuring the value of breakdown voltage in air for electrode separations from 400nm to 45μm using thin film Au lines evaporated on sapphire.
Journal ArticleDOI
Why the long-term charge offset drift in Si single-electron tunneling transistors is much smaller (better) than in metal-based ones: Two-level fluctuator stability
Neil M. Zimmerman,William H. Huber,Brian J. Simonds,Emmanouel Hourdakis,Akira Fujiwara,Yukinori Ono,Yasuo Takahashi,Hiroshi Inokawa,Miha Furlan,Mark W. Keller +9 more
TL;DR: In this article, the authors present a model for the charge offset drift based on the observation of nonequilibrium heat evolution in glassy materials, and obtain a numerical estimate in go...
Journal ArticleDOI
Charge offset stability in tunable-barrier Si single-electron tunneling devices
Neil M. Zimmerman,Brian J. Simonds,Akira Fujiwara,Yukinori Ono,Yasuo Takahashi,Hiroshi Inokawa +5 more
TL;DR: In this paper, the authors demonstrate that in tunable-barrier Si-based SET transistors there is excellent stability, with a drift that is in general less than 0.01e; these devices exhibit some unwanted sensitivity to external perturbations including temperature excursions.
Journal ArticleDOI
Time-Resolved Absorptance and Melt Pool Dynamics during Intense Laser Irradiation of a Metal
Brian J. Simonds,Jeffrey W. Sowards,Josh Hadler,Erik A. Pfeif,Boris Wilthan,Jack Tanner,Chandler Harris,Paul A. Williams,John H. Lehman +8 more
TL;DR: The average absorptances determined optically are compared with calorimetrically determined values, and it is found that the calorimeter severely underestimates the absorbed energy due to mass lost during the spot weld.
Journal ArticleDOI
Portable, high-accuracy, non-absorbing laser power measurement at kilowatt levels by means of radiation pressure
Paul A. Williams,Joshua A. Hadler,Frank C. Maring,Robert Lee,Kyle A. Rogers,Brian J. Simonds,Matthew Spidell,Michelle Stephens,Ari Feldman,John H. Lehman +9 more
TL;DR: A non-traditional optical power meter which measures radiation pressure to accurately determine a laser's optical power output, which permits fast measurements, simplifies power scalability, and allows high-accuracy measurements to be made during use of the laser for other applications.
