zero dispersion wavelengthWe consider hexagonal patterned primitive unit cell based polyethylene index guided Photonic crystal fiber (PCF) design, and report its potential use in high power THz pulse generation and transmission due to variability of zero dispersion wavelength with single design parameter ...
How many different unit cells can a crystal have if the unit cell has all of its unit cells has at least one 90 degrees angle between axes? Which of the three-dimensional primitive lattices has a unit cell where none of the internal angles is 90^o? I...

A hexagonal prism is made up from three primitive unit cells. The conventional hexagonal unit cell, like all others used in defining crystal systems, is a parallelepiped (see Fig. 2.10a and b for example). Sign in to download full-size image Figure 2.9. The hexagonal system of axes. ...
How many are in its primitive cell? Solution Diamond is fcc with two atoms per lattice point, the two atoms being separated by ¼ <1 1 1>. There are four lattice points per cubic unit cell in fcc, and therefore there are eight atoms per cubic unit cell in diamond. The primitive ...
hcp crystals have a lower number of symmetry operations and have an extra structural variable in describing its crystal structure. In contrast to the other two that embrace only one atom in the primitive unit cells in case of pure elements, there are two atoms in the unit cell of hcp elemen...
