rhombohedral lattice

rhombohedral lattice

[¦räm·bō¦hē·drəl ¦lad·əs]
(crystallography)
A crystal lattice in which the three axes of a unit cell are of equal length, and the three angles between axes are the same, and are not right angles. Also known as trigonal lattice.

It can be seen from this figure that doping of La up to 0.4% keeps the rhombohedral lattice intact [21].
It belongs to the rhombohedral lattice R[bar.3]m space group, although a recent paper describes a second [B.sub.4]C phase with monoclinic structure, reopening the discussion about the boron carbide structure [13].
The rhombohedral lattice can also be described as a hexagonal lattice [38], and, in the case of [B.sub.4]C, the hexagonal [c.sub.H] axis is parallel to the longest diagonal of the rhombohedral structure, which contains the three-atom chain (C-B-C).
The electronic band structure of CeS, CeSe, and CeTe in the antiferromagnetic phase along the X-[GAMMA]-L-T-[GAMMA] directions of the first Brillouine zone of the rhombohedral lattice is shown along with the total and partial densities of electronic states in Figures 5(a)-5(c).
The XRD results in Fig.1 indicated that only when distilled water was employed as solvent could the final product achieve pure [Bi.sub.2][Te.sub.3] phase with R3m rhombohedral lattice structure.
