Asymmetric Enhanced Intermixing in Co/Ti Bilayer

October 12, 2021
Author(s)
P Sule, L Kotis, L Toth, M. Menyhard, William F. Egelhoff Jr.
Low-energy ion-beam intermixing has been studied by Auger depth profiling and by molecular dynamics simulations in Co/Ti and Ti/Co bilayers. The agreement between theory and experiment is satisfactory. Both of them suggest the occurrence of the asymmetry

Atomic Transition Probabilities for DyI and DyII

October 12, 2021
Author(s)
M E. Wickliffe, James E. Lawler, Gillian Nave
Atomic transition probabilities for 915 spectral lines of neutral and singly ionized dysprosium are reported. Typical uncertainties are less than +/- 10%. Branching fractions, measured using the 1.0 m Fourier transform spectrometer (FTS) at the National

Atomistic Insights into Disclocation Dynamics in Metal Forming

October 12, 2021
Author(s)
Francesca Tavazza, Anne M. Chaka, Lyle E. Levine
Almost all of the mechanical behavior changes that occur during plastic deformation result from the evolution of dislocation structures. Statistical models, like strain percolation theory, have been developed to understand the transport of dislocations

Barium Strontium Titaanate Thin Film Analysis

October 12, 2021
Author(s)
T Remmel, R Deslattes, S Fujimura, H Honma, H Kobayashi, H Kohno, S M. Owens, J Pedulla, M Schulberg
Barium Strontium Titanate (BST) is under consideration as a high dielectric constant material for a number of semiconductor applications. Because of its very large dielectric constant, BST is seen as an enabling material that will allow the continual

Benchmark Gauging System for a Small-Scale Liquid Hydrogen Tank

October 12, 2021
Author(s)
N T. Van Dresar, James D. Siegwarth
A system to accurately weigh the fluid contents of a small-scale liquid hydrogen test tank has been experimentally verified. It is intended for use as a reference or benchmark system when testing low-gravity liquid quantity gauging concepts in the

Blackbody Radiation Shift in a 43 Ca + Ion Optical Frequency Standard

October 12, 2021
Author(s)
B Arora, M S. Safronova, Charles W. Clark
Motivated by the prospect of an optical frequency standard based on 43Ca+, we calculate the blackbody radiation (BBR) shift of the 4s1/2 - 3d5/2 clock transition, which is a major component of the uncertainty budget. The calculations are based on the
