Three-dimensional heterogeneous integration offers compelling opportunities to enhance the security and trust in the current semiconductor chain while new attack surfaces may emerge.

Staging Cybersecurity Risks for Enterprise Risk Management and Governance Oversight

March 6, 2024
Author(s)
Stephen Quinn, Nahla Ivy, Matthew Barrett, Greg Witte, R.K. Gardner
This document is the third in a series that supplements NIST Interagency/Internal Report (NISTIR) 8286, Integrating Cybersecurity and Enterprise Risk Management (ERM). This series provides additional details regarding the enterprise application of

Laser-power consumption of soliton formation in a bidirectional Kerr resonator

March 5, 2024
Author(s)
Jizhao Zang, Su-Peng Yu, Haixin Liu, Yan Jin, Travis Briles, David Carlson, Scott Papp
Laser sources power extreme data transmission as well as computing acceleration, access to ultrahigh-speed signaling, and sensing for chemicals, distance, and pattern recognition. The ever-growing scale of these applications drives innovation in multi

Topology as a limiting factor in mechanical properties for disordered networks

March 5, 2024
Author(s)
Marcos Reyes-Martinez, Edward Barron III, Dohgyu Hwang, Christopher Soles, Michael Bartlett, Edwin Chan
Disordered networks are ubiquitous in both the natural and synthetic worlds. Depending on the application, some are extremely soft while others are rigid. However, how network topology and intrinsic material properties combine to control deformation and

Bottom-up Au Filling of Trenches in Curved Wafers

March 4, 2024
Author(s)
Daniel Josell, Thomas P. Moffat, Thomas Gnaupel-Herold, David Raciti, Martin Stauber, Yu Q, Liyang Chen, M Rawlik, Marco Stampanoni, Lucia Romano
A 〖Bi〗^(3+)-stimulated Au electrodeposition process in slightly alkaline 〖Na〗_3 Au(〖SO〗_3 )_2+〖Na〗_2 〖SO〗_3 electrolytes has been previously demonstrated for void-free extreme bottom-up filling of trenches with aspect ratios (height/width) exceeding 60 in

Isotopic effects on in-plane hyperbolic phonon polaritons in MoO3

March 4, 2024
Author(s)
Jeremy Schultz, Sergiy Krylyuk, Jeffrey Schwartz, Albert Davydov, Andrea Centrone
Hyperbolic phonon polaritons (HPhPs), hybrids of light and lattice vibrations in polar dielectric crystals, empower nano-photonic applications by enabling the confinement and manipulation of light at the nanoscale. Molybdenum trioxide (α-MoO3) is a

Reduction-Induced Magnetic Behavior in LaFeO3-d Thin Films

March 4, 2024

Nathan Arndt, Eitan Hershkovitz, Labdhi Shah, Kristoffer Kjaernes, Chao-Yao Yang, Purnima Balakrishnan, Mohammed Shariff, Shaun Tauro, Daniel Gopman, Brian Kirby, Alexander Grutter, Thomas Tybell, Honggyu Kim, Ryan Need
The effect of oxygen reduction on the magnetic properties of LaFeO3−δ (LFO) thin films was studied to better understand the viability of LFO as a candidate for magnetoionic memory. Differences in the amount of oxygen lost by LFO and its magnetic behavior

Debye-Waller Effects in Bethe-Salpeter Calculations

March 3, 2024
Author(s)
Eric Shirley, Joseph Woicik
We present a method to incorporate Debye-Waller effects on core-excitation spectra in methods other than real-space multiple scattering formulations. The method draws ideas from multiple-scattering theory to realize effects of variations in interatomic
