Porous Zero-Mode Waveguides for Picogram-Level DNA Capture

Author(s)
Vivek Jadhav, David Hoogerheide, Jonas Korlach, Meni Wanunu
We have recently shown that nanopore zero-mode waveguides are effective tools for capturing picogram levels of long DNA fragments for single-molecule DNA...

Low-Carrier Density and Fragile Magnetism in a Kondo Lattice System

Author(s)
Binod K. Rai, Iain W. H. Oswald, Wenjing Ban, C.-L. Huang, V. Loganathan, A. M. Hallas, M. N. Wilson, G. M. Luke, Leland Harriger, Qingzhen Huang, Y. Li, Sami Dzsaber, Julia Y. Chan, N. L. Wang, Silke Paschen, Jeffrey W. Lynn, Andriy H. Nevidomskyy, Pengcheng Dai, Q. Si, E. Morosan
Known low carrier Kondo systems evolve from metallic non-magnetic analogues, while a recent theoretical model for the dilute carrier Kondo limit predicts...

RF waveform synthesizers with quantum-based voltage accuracy for communications metrology

Author(s)
Peter F. Hopkins, Justus A. Brevik, Manuel C. Castellanos Beltran, Nathan E. Flowers-Jacobs, Anna E. Fox, David I. Olaya, Christine A. Donnelly, Paul D. Dresselhaus, Samuel P. Benz
We report on NIST’s development of Josephson junction-based programmable reference sources to synthesize quantum-accurate, spectrally-pure waveforms for...

Stacked Josephson Junctions as inductors for SFQ circuits

Author(s)
Manuel C. Castellanos Beltran, David I. Olaya, Adam J. Sirois, Paul D. Dresselhaus, Samuel P. Benz, Peter F. Hopkins
In order for Single Flux Quantum (SFQ) circuits to be scaled to densities needed for large-scale integration, typical lithographically-patterned circuit...

In Situ Back-Contact Passivation Improves Photovoltage and Fill Factor in Perovskite Solar Cells

Author(s)
Lee J. Richter, Ahmad R. Kirmani, Furui Tan, Hairen Tan, Wei Mingyang, Makhsud I. Saidaminov, Mengxia Liu, Mei Anyi, Peicheng Li, Chih-Shan Tan, Xiwen Gong, Yongbiao Zhao, Ziru Huang, James Z. Fan, Rafael Quintero-Bermudez, Kim Junghwan, Yicheng Zhao, Oleksandr Voznyy, Zheng-Hong Lu, Weifeng Zhang, Edward H. Sargent, Bowen Zhang, Yueye Gao, Feng Zhang
Organic–inorganic hybrid perovskite solar cells (PSCs) have seen a rapid rise in power conversion efficiencies in recent years; however, they still suffer from...

High Temperature Singlet-Based Magnetism from Hund's Rule Correlations

Author(s)
Lin Miao, Rourav Basak, Sheng NMN Ran, Yishuai Xu, Erica Kotta, Haowei He, Jonathan D. Denlinger, Yi-De Chuang, Yang Zhao, Zhijun Xu, Jeffrey W. Lynn, J. R. Jeffries, Shanta Ranjan Saha, Ioannis Giannakis, Pegor Aynajian, Chang-Jong Kang, Yilin Wang, Gabriel Kotliar, Nicholas Butch, L. Andrew Wray
Novel electronic phenomena frequently form in heavy fermions as a consequence of the mutual nature of localization and itineracy of f-electrons. On the...

Inline Laser Power Measurement by Photon Momentum

Author(s)
John H. Lehman, Paul A. Williams, Daniel W. Rahn, Kyle A. Rogers
We present a measurement scheme and instrumentation for quantifying laser power by means of photon momentum. The optical design is optimized such that the...

Exposure Study on the Aging of PTFE and Ceramic Diffusers

Author(s)
Benjamin K. Tsai, Catherine C. Cooksey, David W. Allen, Christopher C. White, Walter E. Byrd, Deborah S. Jacobs
This paper describes efforts to quantify the effects of aging in the ultraviolet (UV) on polytetrafluoroethylene (PTFE) and ceramic samples. Long term UV aging...

Author(s)
William J. Boettinger, Dale E. Newbury, Nicholas W. Ritchie, Maureen E. Williams, Ursula R. Kattner, Eric Lass, Kil-Won Moon, Michael B. Katz
Differential thermal analysis (DTA) and microstructural and microprobe measurements of DTA and as-cast Ni-Re alloys with compositions between 0.20 and 0.44 mass...

Nano-kelvin DC and AC Meissner-TES Thermometry

Author(s)
Solomon I. Woods, Adriaan C. Carter, Timothy M. Jung, Dana R. Defibaugh
The Meissner-TES is a relatively new type of high resolution cryogenic thermometer based upon a transition edge sensor (TES) which employs the magnetic...
