Towards single atom devices for quantum information and metrology: weak localization in embedded phosphorus delta layers in silicon

June 29, 2017
Author(s)
Joseph A. Hagmann, Xiqiao Wang, Pradeep N. Namboodiri, Jonathan E. Wyrick, Roy E. Murray, Michael D. Stewart, Richard M. Silver, Curt A. Richter
The key building block for devices based on the deterministic placement of dopants in silicon is the formation of phosphorus dopant monolayers and the overgrowth of high quality crystalline Si. Lithographically defined dopant delta-layers can be formed

A Reassessment of Absolute Energies of X-ray L Lines of Lanthanide Metals

HMFEv - An Efficient Multivariate Signature Scheme

June 28, 2017
Author(s)
Albrecht R. Petzoldt, Ming-Shing Chen, Jintai Ding, Bo-Yin Yang
Multivariate Cryptography, as one of the main candidates for establishing post-quantum cryptosystems, provides strong, efficient and well-understood digital signature schemes such as UOV, Rainbow, and Gui. While Gui provides very short signatures, it is

Immersion coefficient for the Marine Optical BuoY (MOBY) radiance collectors

June 28, 2017
Author(s)
Michael Feinholz, B. Carol Johnson, Kenneth Voss, Mark A. Yarbrough, Stephanie J. Flora
The immersion coefficient accounts for the difference in calibration for a radiometer placed in the air versus water or another medium. The immersion coefficient for the radiance collectors on the Marine Optical BuoY (MOBY) were modeled and measured. The

Neutral and Charged Inter-Valley Biexcitons in Monolayer MoSe2

June 28, 2017
Author(s)
Lixiang Xu, Judith Specht, Philip Nagler, Kha Tran, Akshay Singh, Chandriker K. Dass, Andreas Knorr, Xiaoqin Li, Galan Moody
In atomically thin transition metal dichalcogenides (TMDs), reduced dielectric screening of the Coulomb interaction leads to strongly correlated many-body states, including excitons and trions, that dominate the optical properties. Higher-order states

Part-of-Math Tagging and Applications

June 28, 2017
Author(s)
Abdou S. Youssef
Much of the mathematical literature, old and new, is online and mostly in natural-language form. Therefore, math content processing presents some of the same challenges faced in natural language processing (NLP), such as math disambiguation and math

Revisiting Shape Selectivity in Liquid Chromatography for Polycyclic Aromatic Hydrocarbons (PAHs) - Six-Ring and Seven-Ring Cata-condensed PAH Isomers of Molecular Mass 328 Da and 378 Da

June 28, 2017
Author(s)
Jorge O. Ona Ruales, Lane C. Sander, Walter Brent Wilson, Stephen Wise
The relationship of reversed-phase liquid chromatography retention on a polymeric C18 stationary phase and the shape of polycyclic aromatic hydrocarbons (PAHs) was investigated for three-ring to seven-ring cata-condensed isomers. We report the first

Semantic Preserving Bijective Mappings of Mathematical Formulae between Word Processors and Computer Algebra Systems

Author(s)
Howard S. Cohl, Bonita V. Saunders, Marjorie A. McClain, Moritz Schubotz, Joon Bang, Juergen Gerhardt, Andre Greiner Petter
There are many different approaches to represent mathematical expressions on computers. Word processors like LaTeX offer the ability to render mathematical expressions as one would write these on paper. Using LaTeX, LaTeXML, and tools generated for use in

Smart Production Systems: Architecture and Application to multi-job manufacturing

June 28, 2017
Author(s)
Pooya Alavian, Peter O. Denno, Semyon Meerkov
Smart Production Systems (SPS) are manufacturing systems capable of self-diagnosing and providing the operation management with an advice concerning performance improvements, along with rigorously quantified outcomes of their potential deployment. This

The Impact of Organic Additives On Copper Trench Microstructure

June 28, 2017
Author(s)
James B. Marro, Chukwudi A. Okoro, Yaw S. Obeng, Kathleen C. Richardson
Organic additives are typically used in the pulse electrodeposition of copper (Cu) to prevent void formation during the filling of high aspect ratio features. In this work, the role of bath chemistry as modified by organic additives was investigated for

Valley Phase and Voltage Control of Coherent Manipulation in Si Quantum Dots

June 28, 2017
Author(s)
Neil M. Zimmerman, Peihao Huang, Dimitrie Culcer
With any roughness at the interface of an indirect-bandgap semiconducting dot, the phase of the valley-orbit coupling can take on a random value. This random value, in double quantum dots, causes a large change in the exchange splitting. We demonstrate a
