Crystallographic Data for the Hexagonal Crystal System
Nuclear Science and Engineering, 1962 Interplanar angles for the hexagonal system were calculated on a high- speed digital computer for axial ratios c/a from 1.500 to 2.000 at intervals of 0.010. The results, rounded off to the third decimal place, are tabulated, and a nomogram is also given for determining the angles within 0.5 deg . A table of interplanar angles is given for the elements

Key Engineering Materials, 2020 Hexagonal crystal system materials have very important applications in modern society. Dielectric constant tensor of hexagonal crystal system materials is simplified only by the formula in a hexagonal coordinate system, not by the formula often seen in current Chinese solid state physics textbooks.

Contrast factors of dislocations in the hexagonal crystal system
Journal of Applied Crystallography, 2002 Strain anisotropy can be well accounted for by the dislocation model of lattice distortion. In a texture-free powder or polycrystal, or if all possible Burgers vectors are equally populated, the dislocation contrast factors are a linear function of the fourth-order invariants of thehklindices.

Photonic crystal ring resonator based add-drop filter using hexagonal rods for CWDM systems
Optoelectronics Letters, 2011 In this paper, theoretical analysis of two-dimensional photonic crystal ring resonator (2D PCRR) based add-drop filter (ADF) is presented for coarse wavelength division multiplexing (CWDM) system to drop a channel at 1511 nm using hexagonal rods that are positioned in the square lattice.

Rotation boundaries and crystal growth in the hexagonal system
Philosophical Magazine, 1969 Abstract A rotating crystal x-ray diffraction technique has been employed for the measurement of rotation boundary angles in natural graphite crystals, and the values obtained have been compared with those predicted by coincidence boundary theory. It is shown that for natural graphite crystals these values do not correlate with theory, while previous ...

Facile synthesis of concave gold nanoplates in hexagonal liquid crystal made of SDS/water system
Chemical Communications, 2010 Concave gold nanoplates are obtained in hexagonal liquid crystal (LLC) made of SDS (sodium dodecyl sulfate)/glycine/HAuCl(4) aqueous solution system where glycine plays the key role. All plates are single-crystals, characterized by {111} facets, with concave centers of regular hexagonal or triangular shapes, and with better electrocatalytic activity ...

Total reflection and surface scattering of soft X-rays on the Si-SiO2system and hexagonal BN crystal
Journal of Physics: Condensed Matter, 1995 Reflection spectra for different grazing angles and reflectivity angular dependences of the Si-SiO2 system with different dioxide thicknesses have been measured in the energy range 40-850 eV, including the Si L2.3 and O K absorption edges. The angular dependences have been used for the dielectric constant determination.

Green’s tensor for crystals of the hexagonal system
Physics of the Solid State, 2013 Expressions for components of the Green’s tensor of the basic equation of the elasticity theory for hexagonal system crystals have been obtained using the Lifshitz-Rozentsveig method. A problem is in principle reduced to finding the roots of a sixth-order algebraic equation. They are either complex or purely imaginary for all known hcp metals.
