Interlayer spacings in carbon nanotubes

Physical Review B, 1993
Electron and x-ray-diffraction studies of nanotubes have revealed that the distances between the graphitic sheets are larger by a few percent than those in bulk graphite. The mean value of the interlayer spacings is 0.344\ifmmode\pm\else\textpm\fi{}0.001 nm.

Sharpening filter for interlayer prediction

2014 IEEE Visual Communications and Image Processing Conference, 2014
This paper describes method of predicting enhancement layer pictures from base layer pictures for Scalable extension of High Efficiency Video Coding (SHVC). SHVC stream contains multiple layers of different types of scalability: temporal, spatial or quality.

Formation of epitaxial CoSi2 by a Cr or Mo interlayer: Comparison with a Ti interlayer

Journal of Applied Physics, 2001
The influence of Cr and Mo on phase formation and preferential orientation of CoSi2 is reported. Three different regimes are distinguished, depending on the thickness of the interlayer. For a thin interlayer or a capping layer, CoSi forms first, as in the standard Co/Si reaction. The remaining Cr or Mo can be considered as a contaminant that is present

Interlayer optical conductivity of a superconducting bilayer

Physical Review B, 1994
We employ the Bardeen-Cooper-Schrieffer theory to calculate the frequency-dependent interlayer conductivity of a superconducting bilayer, the two layers of which are coupled by weak single-particle tunneling. The effect of the superconducting transition on the normal-state absorption band is to blue-shift and broaden it, while causing the peak ...

Interlayer Exchange Coupling of Ferromagnetic Films Across Semiconducting Interlayers

2004
We review our observations of surprisingly strong antiferromagnetic interlayer exchange coupling across Si-rich Fe 1−x Si x spacers, which becomes stronger with increasing Si content, x, in the spacer. We show that the nominally pure (x = 1) spacers that mediate the strongest coupling act at the same time as a tunneling barrier for electric transport ...

Orientation dependence of interlayer coupling and interlayer moments in Fe/Cr multilayers

Physical Review B, 1997
The relationship between indirect exchange coupling and interlayer d-electron magnetic moments is studied using magnetometry and x-ray magnetic circular dichroism (XMCD) in Fe/Cr multilayers. Multilayers are simultaneously prepared with growth axes along different crystallographic orientations to determine the orientation dependence of these properties.

Theory of interlayer magnetic coupling

Physical Review B, 1995
A theory of interlayer exchange coupling is presented. A detailed and comprehensive discussion of the various aspects of the problem is given. The interlayer exchange coupling is described in terms of quantum interferences due to confinement in ultrathin layers. This approach provides both a physically transparent picture of the coupling mechanism, and

HRTEM investigation of intralayer and interlayer stacking defects and pyrophyllite interlayers in illite

Mineralogical Magazine, 2010
AbstractMetastable authigenic 1Millite from shale of diagenetic grade has been studied using a high-resolution transmission electron microscope (HRTEM) equipped with energy-dispersive spectrometer, X-ray diffraction, and scanning electron microscope. The illite occurs as deformed flakes deficient in interlayer K+cations with 0.6 per half cell, and with

Interlayer bond polarizability model for interlayer phonons in van der Waals heterostructures

Nanoscale
The interlayer bond polarizability model is improved to quantitatively understand the twist-angle and excitation-energy dependent Raman intensity profile of layer-breathing modes in polynary van der Waals heterostructures.
