Shape of Hollow Dislocation Cores: Elastic and Anisotropic Surface Energy Effects

October 12, 2021
Author(s)
David J. Srolovitz, N Sridhar, J P. Hirth, John W. Cahn
Evidence for the existence of hollow core dislocations has existed for nearly forty years. Such hollow cores are often found in growth spirals associated with screw dislocations. Examples of this type of morphology may be found in silicon carbide, copper

Simulating Thermal Response of EB-PVD Thermal Barrier Coating Microstructures

October 12, 2021
Author(s)
M Bartsch, U Schulz, J M. Dorvaux, O Lavigne, Lin-Sien H. Lum, Stephen A. Langer
As ceramic thermal barrier coatings (TBC) are used in more critical applications in advanced engines, knowing basic physiproperties of TBC's is essential for design and reliability assessment. In particular, knowledge of thermal conductivity is cruciin

Simulation of a Single Asperity Impacts at Head-Disk Interface

October 12, 2021
Author(s)
Tze J. Chuang, Stephen M. Hsu
During the track accessing mode of a hard disk drive, the flying height of the slider over the disk surface becomes smaller and smaller as the demand in data storage a real density increases. As a result, the propensity of glide avalanche is bound to

SiO 2 /Si 3 N 4 /A1 2 O 3 Stacks on Silicon for Scaled-Down Memory Devices: Effects of Interfaces and Thermal Annealing

October 12, 2021
Author(s)
M Lisiansky, A Heiman, M Kovler, Y Roizin, Igor Levin, A Gladkikh, M Oksman, R Edrei, A A. Hofman, Y Shnieder, T Claasen
Effects of interfaces and thermal annealing on the electrical performance of the SiO2/Si3N4/A12O3 (ONA) stacks in non-volatile memory devices were investigated. Structural and electrical characterization demonstrated the principal role of the Si3N4/A12O3

Sixth Annual Report on Federal Agency Use of Voluntary Consensus Standards

October 12, 2021
Author(s)
K L. McIntyre, M B. Moore
Document is the Annual Report on Federal Agency Use of Voluntary Consensus Standards required to be submitted by NIST the office of Management Budget (OMB) under the National Technology Transfer and Advancement Act and OMB Circular A-119. It contains a

Small Angle Neutron Scattering Measurement of Silicon Nanoparticle Size Distribution

October 12, 2021
Author(s)
Jonghoon Choi, Shih-Huang Tung, Nam S. Wang, Vytas Reipa
We have determined the particle size distribution profiles of octane terminated silicon nanoparticle suspensions, produced using the sonication of electrochemically etched Si wafer. Small angle neutron scattering data was analyzed separately in the high (0

Soft X-Ray Fluorescence Studies of Solids

October 12, 2021
Author(s)
J A. Carlisle, Steven R. Blankenship, R N. Smith, Eric L. Shirley, L J. Terminello, J J. Jia, T A. Callcott, D L. Ederer
Resonant inelastic x-ray scattering (RIXS) has been observed in many systems above and below their core threshold. Below threshold, inelastic-loss features are observed, which disperse linearly with excitation energy, but as the excitation increases above

Software Specifications for Build LCC

October 12, 2021
Author(s)
M A. Ehlen, S Fuller
The report provides a list of guidelines for integrating two software programs that are extensively used by agencies of the federal government to evaluate the cost effectiveness of building-related investments, mainly for energy and water conservation

Solidus Phase Relationships in the AO-Al 2 O 3 -Nb 2 O 5 (A = Ca, Sr) Systems

October 12, 2021
Author(s)
Julia Y. Chan, Wilma Feb-Ayala, L D. Rotter, Igor Levin, Richard G. Geyer
Dielectric ceramics for wireless communications exhibiting modest permittivity, high quality factor (Q), and near-zero temperature coefficient are needed for high frequency, high power applications. Efforts are in progress to replace Ta 2O 5-based ceramics
