Model for the Bipolar Amplification Effect

December 10, 2021
Author(s)
James Ashton, Stephen Moxim, Ashton Purcell, Patrick Lenahan, Jason Ryan
We present a model based on Fitzgerald-Grove surface recombination for the bipolar amplification effect (BAE) measurement, which is widely utilized in electrically detected magnetic resonance (EDMR) to measure reliability and performance-limiting interface

Opportunities in electrically tunable 2D materials beyond graphene: Recent progress and future outlook

November 30, 2021
Author(s)
Tom Vincent, Jiayun liang, simrjit singh, eli castanon, xiaotian zhang, deep jariwala, olga kazakova, zakaria al-balushi, Amber McCreary
The interest in two-dimensional and layered materials continues to expand, driven by the compelling properties of individual atomic layers that can be stacked and/or twisted into synthetic heterostructures. The plethora of electronic properties as well as

Effect of Chloride on Microstructure in Cu Filled Microscale Through Silicon Vias

November 2, 2021
Author(s)
Daniel Josell, Thomas P. Moffat, Trevor Braun
The microstructure of copper filled through silicon vias deposited in a CuSO4 + H2SO4 electrolyte containing micromolar concentrations of deposition rate suppressing poloxamine and chloride additives is explored using electron backscatter diffraction

Dual current anomalies and quantum transport within extended reservoir simulations

October 19, 2021
Author(s)
Gabriela Wojtowicz, Justin E. Elenewski, Marek Rams, Michael P. Zwolak
Quantum transport simulations are rapidly evolving, including the development of well–controlled tensor network techniques for many– body transport calculations. One particularly powerful approach combines matrix product states with extended reservoirs —

Collector Series-Resistor to Stabilize a Broadband 400 GHz Common-Base Amplifier

October 14, 2021
Author(s)
Jerome Cheron, Dylan Williams, Richard Chamberlin, Miguel Urteaga, Kassi Smith, Nick Jungwirth, Bryan Bosworth, Chris Long, Nate Orloff, Ari Feldman
The indium phosphide (InP) 130 nm double-heterojunction bipolar transistor (DHBT) offers milliwatts of output power and high signal amplification in the lower end of the terahertz frequency band when the transistor is used in a common-base configuration

Performance of Reservoir Discretizations in Quantum Transport Simulations

September 29, 2021
Author(s)
Justin E. Elenewski, Gabriela Wojtowicz, Marek Rams, Michael P. Zwolak
Quantum transport simulations require a level of discretization, often achieved through an explicit representation of the electronic reservoirs. These representations should converge to the same continuum limit, though there is a trade-off between a given

Deterministic Tagging Technology for Device Authentication

September 16, 2021
Author(s)
Jungjoon Ahn, Joseph J. Kopanski, Yaw S. Obeng, Jihong Kim
This paper discusses the development of a rapid, large-scale integration of deterministic dopant placement technique for encoding information in physical structures at the nanoscale. The doped structures inherit identical and customizable radiofrequency

Impact ionization-induced bistability in CMOS transistors at cryogenic temperatures for capacitorless memory applications

July 29, 2021
Author(s)
Alexander Zaslavsky, Curt A. Richter, Pragya Shrestha, Brian Hoskins, Son Le, Advait Madhavan, Jabez J. McClelland
Cryogenic operation of complementary metal oxide semiconductor (CMOS) silicon transistors is crucial for quantum information science, but it brings deviations from standard transistor operation. Here we report on sharp current jumps and stable hysteretic

A System for Validating Resistive Neural Network Prototypes

July 27, 2021
Author(s)
Brian Hoskins, Mitchell Fream, Matthew Daniels, Jonathan Goodwill, Advait Madhavan, Jabez J. McClelland, Osama Yousuf, Gina C. Adam, Wen Ma, Muqing Liu, Rasmus Madsen, Martin Lueker-Boden
Building prototypes of heterogeneous hardware systems based on emerging electronic, magnetic, and photonic devices is an increasingly important area of research. On the face of it, the novel implementation of these systems, especially for online learning

National Institute of Standards and Technology Environmental Scan 2020

February 9, 2021
Author(s)
Heather Evans, Kristen K. Greene, William M. Healy, Elizabeth Hoffman, Kate Rimmer, Anna V. Sberegaeva, Neil M. Zimmerman
The 2020 National Institute of Standards and Technology Environmental Scan provides an analysis of key external factors that could impact NIST and the fulfillment of its mission in coming years. The analyses were conducted through four separate lenses

Quantum dot lasers - history and future prospects

January 29, 2021
Author(s)
Richard Mirin, John E. Bowers, Justin Norman
We describe the initial efforts to use molecular beam epitaxy to grow InAs quantum dots on GaAs via the Stranski-Krastanow transition. We then discuss the initial efforts to use these quantum dots to demonstrate quantum dot lasers. We discuss the

Recent advances in superconducting nanowire single-photon detector technology for exoplanet transit spectroscopy in the mid-infrared

January 12, 2021
Author(s)
Varun Verma, Jeff Chiles, Adriana Lita, Richard Mirin, Sae Woo Nam, Yao Zhai, Adam McCaughan, Emma Wollman, Alexander Walter, Boris Korzh, Jason Allmaras, Ekkehart Schmidt, S. Frasca, Matthew Shaw
Superconducting nanowire single-photon detectors, or SNSPDs, have become the highest-performing class of single-photon detectors in the near-IR. At telecom wavelengths, SNSPDs have demonstrated detection effi- ciency above 95%, intrinsic dark count rates

Dual Josephson impedance bridge: towards a universal bridge for impedance metrology

October 22, 2020

Frederic Overney, Nathan Flowers-Jacobs, Blaise Jeanneret, Alain Rufenacht, Anna Fox, Paul Dresselhaus, Samuel Benz
This paper presents a full characterization of a Dual Josephson Impedance Bridge (DJIB) at frequencies up to 80 kHz by using the DJIB to compare the best available impedance standards that are (a) directly traceable to the quantum Hall effect, (b) used as

A Cryogenic Quantum-Based RF Source

September 10, 2020
Author(s)
Jason Underwood, Stephen Pfeiffer, Geoffrey Palo
For accurate realization of the ac volt, the Josephson Arbitrary Waveform Synthesizer (JAWS) must not be overly loaded by the electrical network in which it is used. The interaction between the on-chip inductance and the stray capacitance in the network
