Interlayer exchange coupling in magnetic multilayers
… recently. We present a theoretical study of the interlayer coupling in magnetic multilayers using two theoretical approaches. One such approach is to invoke the Ruderman-Kittel-Kasuya-Yosida (RKKY) theory, which is more relevant to the multilayer system in which localized magnetic moments …

NDT to characterize 3D printed concrete interlayer bonds
… testing (NDT) techniques that characterize the interlayer bond quality (bond strength) of 3D printed concrete in situ. An experimental study applied four NDT methods (x-ray radiography, ultrasonic pulse velocity (UPV), vibration resonance, and multi-element array ultrasonics) to idealized, …

Evaluation of interlayer bonding in hot mix asphalt pavements
… (FWD) data for use in quantifying the level of interlayer bonding achieved in pavements. Data was obtained and used from the Federal Aviation Administration's (FAA) National Airport Pavement Test Facility located in Atlantic City, New Jersey. In this test facility, a section of the pavement had …

Quantitative and consistent tests for interlayer adhesion in laminated glass
The use of the double cleavage drilled compression (DCDC) for determining the toughness of glass/PVB interfaces has been examined. Experiments were conducted on two different types of samples: low and high adhesion. Stress and fracture analysis was conducted using the finite element method. The …

Interlayer optical response of yttrium barium (copper (cobalt, zinc)) oxide
… bilayers dominate the doping dependence of interlayer coupling in $\rm YBa\sb2(Cu\sb{1 - y}M\sb{y})\sb3O\sb{6 + x}$ (M = Co, Zn). The slight decrease in $\sigma\sb{\rm c}(\omega)$ observed with Zn substitution suggests that the charge dynamics in the CuO$\sb2$ planes play at best a minor …

Layered Double Hydroxides: Morphology, Interlayer Anion, and the Origins of Life
… is the uptake and orientation of anions into the interlayer. Questions about iron cyanide interlayer anions have been posed. Fourier transform infared spectroscopy and powder x-ray diffraction have been used to investigate these topics. It was found that factors such as orientation, anion charge, …

Green function studies of the interlayer exchange coupling in magnetic multilayers
The Interlayer Exchange Coupling (IEC) of magnetic multilayers has been one of the most studied problems in condensed matter physics for the last decade. It is found that for a multilayer structure in which magnetic layers are separated by a spacer, the magnetic moments of each layer orient …

Electrical study of molybdenum in silicon and fluorinated SiO₂ for interlayer dielectrics
Molybdenum is unintentionally introduced into silicon at various points in semiconductor processing. This introduction is a concern because molybdenum introduces a deep level state into the forbidden gap of silicon, degrading minority carrier lifetime. In this project, DLTS was used to measure the …

Interlayer Defect Effects on the Phonon Properties of Bilayer Graphene and its Nanoribbon
Phonon properties of AB (Bernal) stacked bilayer graphene (BLG) with various types of defects have been investigated theoretically. Forced Vibrational (FV) method has been employed to compute the phonon modes of disordered BLG. A downward linear shift of E2g mode frequencies has been observed with …

Investigation of Adhesive and Electrical Performance of Waterborne Epoxies for Interlayer Dielectric Material
The primary differences between the solventborne and waterborne epoxy printed circuit board (PCB) impregnating resins arise from the distinct physical compositions and drying characteristics of the polymer solution and the latex emulsion. The presence of residual surfactant from the waterborne …

Infrared Study of Oxidized and Reduced Nontronite and Ca-K Competition in the Interlayer
Ca and K selectivity in the interlamaller space of the unaltered, reduced, and reoxidized ferruginous smectite (SWa-1) was studied. The results of this study can be applied to estimate fertilizer K availability in the production field. Cation exchange method was used in this study. In the unaltered …

Particle generation in a chemical vapor deposition/plasma-enhanced chemical vapor deposition interlayer dielectric tool
The interlayer dielectric plays an important role in multilevel integration. Material choice, processing, and contamination greatly impact the performance of the layer. In this study, particle generation, deposition, and adhesion mechanisms are reviewed. In particular, four important sources of …

Fracture of the interlayer junction of the shell from a deep-sea hydrothermal vent gastropod
There is considerable amount of interest in the hierarchical nanomechanical processes that contribute to property amplification of biomaterials. An investigation of these processes and the quantification of the mechanical properties and structure of a biomaterial multilayer is determined. The …
