Smallest repeating unit of crystal lattice
Webb5 mars 2024 · The smallest repeating unit in a HCP crystal contains 6 atoms. Although its density is the same as that of a FCC crystal, it needs 6 atoms to describe its layering. Interestingly, body-centered cubic crystals can be described with only 2 atoms per unit cell, but have a density of only 68% (they are not close-packed). Ref 2 Webb2 sep. 2024 · The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α, β, γ).
