Enhanced Atomic Precision Fabrication by Adsorption of Phosphine into Engineered Dangling Bonds on H-Si Using STM and DFT

November 1, 2022
Author(s)
Jonathan Wyrick, Xiqiao Wang, Pradeep Namboodiri, Ranjit Kashid, Fan Fei, Joseph Fox, Richard M. Silver
Doping of Si using the scanning probe technique of hydrogen depassivation lithography has been shown to enable placing and positioning small numbers of P atoms with nanometer accuracy. Several groups have now used this capability to build devices that

Frustrated Magnetic Interactions and Quenched Spin Fluctuations in CrAs

November 1, 2022
Author(s)
Yayuan Qin, Yao Shen, Yiqing Hao, Hongliang Wo, Shoudong Shen, Russell A. Ewings, Yang Zhao, Leland Harriger, Jeffrey Lynn, Jun Zhao
The discovery of pressure-induced superconductivity in helimagnets (CrAs, MnP) has attracted significant interest in understanding the relationship between complex magnetism and unconventional superconductivity. However, the nature of the magnetism and

Simplified algorithms for adaptive experiment design in parameter estimation

November 1, 2022
Author(s)
Robert D. McMichael, Sean Blakley
In experiments to estimate parameters of a parametric model, Bayesian experiment design allows measurement settings to be chosen based on utility, i.e. the predicted improvement of parameter distributions due to modeled measurement results. In this paper

Visualization of multi-orientational ordering within a single domain of donor non-fullerene acceptor blends

November 1, 2022
Author(s)
Eliot Gann, Christopher McNeill, Urvashi Bothra, Pramiti Hui, Wen Liang Tanc, Hariprasad Venugopal, Chandramouli Subramaniam, Amelia C.Y. Liu, Dinesh Kabra
We have studied the tailored micron-scale phase-separated bulk heterojunction (BHJ) morphology of the well-known polymer (PTB7-Th) and a narrow bandgap acceptor 2,2'-[[4,4,9,9-Tetrakis(4-hexylphenyl)-4,9-dihydro-s-indaceno [1,2-b:5,6-b']dithiophene-2,7

Vitamin E does not Disturb Polyunsaturated Fatty Acid Lipid Domains

November 1, 2022
Author(s)
Mitchell DiPasquale, Michael H. Nguyen, Stuart R. Castillo, Isabelle J. Dib, Elizabeth Kelley, Drew Marquardt
The antioxidant function of vitamin E in biomembranes remains a prominent topic of discussion. As its limitations as an antioxidant persist and novel functions are discovered, our understanding of the role of vitamin E becomes increasingly enigmatic. As a

Convergent close-coupling calculations of electron scattering on HeH+

October 31, 2022
Author(s)
Barry I. Schneider
We use the molecular convergent close-coupling (MCCC) method to perform calculations of 10–1000 eV electron scattering on the ground state of HeH+. Cross sections are presented for excitation of the n = 2−3 singlet and triplet states (where n is the united

Speed, the double edge sword of the Industry 4.0

October 31, 2022
Author(s)
Marion Toussaint, Sylvere Krima, Allison Barnard Feeney, Herve Panetto
The recent digital transformation of the manufacturing world led to numerous benefits, from higher quality products to increased productivity and reduced time to market. In this digital world, data has become a critical element in many essential decisions

Synthesis, Structure, Te Alloying, and Physical Properties of CuSbS2

October 30, 2022
Author(s)
Dean Hobbis, Kaya Wei, Hsin Wang, Joshua B. Martin, George S. Nolas
Materials with very low thermal conductivities continue to be of interest for a variety of applications. We synthesized CuSbS2 employing a mechanical alloying technique in order to investigate its physical properties. The trigonal pyramid arrangement of
