  2. Cubic crystal system - Wikipedia

    en.wikipedia.org/wiki/Cubic_crystal_system

    This structure is often confused for a body-centered cubic structure because the arrangement of atoms is the same. However, the caesium chloride structure has a basis composed of two different atomic species. In a body-centered cubic structure, there would be translational symmetry along the [111] direction.

    This type of structural arrangement is known as cubic close packing (ccp). The unit cell of a ccp arrangement of atoms is the face-centered cubic (fcc) unit cell. This is not immediately obvious as the closely packed layers are parallel to the {111} planes of the fcc unit cell. There are four different orientations of the close-packed layers.

    English: A body centered cubic lattice has two pattern per unit cell: the patterns at each vertex are shared between 8 neighbouring cells. Français : Un réseau cubique centré a deux motifs par maille élémentaire : les motifs à chaque sommet sont partagés avec les 8 mailles voisines.

  6. Supercell (crystal) - Wikipedia

    en.wikipedia.org/wiki/Supercell_(crystal)

    For example, during phonon calculations by the small displacement method, phonon frequencies in crystals are calculated using force values on slightly displaced atoms in the supercell. Another very important example of a supercell is the conventional cell of body-centered (bcc) or face-centered (fcc) cubic crystals.

  7. Unit cell - Wikipedia

    en.wikipedia.org/wiki/Unit_cell

    A primitive cell is a unit cell that contains exactly one lattice point. For unit cells generally, lattice points that are shared by n cells are counted as ⁠ 1 / n ⁠ of the lattice points contained in each of those cells; so for example a primitive unit cell in three dimensions which has lattice points only at its eight vertices is considered to contain ⁠ 1 / 8 ⁠ of each of them.

    en.wikipedia.org/wiki/Wigner–Seitz_cell

    The Wigner–Seitz cell of the face-centered cubic lattice is a rhombic dodecahedron. [9] In mathematics, it is known as the rhombic dodecahedral honeycomb . The Wigner–Seitz cell of the body-centered tetragonal lattice that has lattice constants with c / a > 2 {\displaystyle c/a>{\sqrt {2}}} is the elongated dodecahedron .

    The diamond cubic crystal structure occurs for example diamond , tin, and most semiconductors. There are 8 atoms in the cubic unit cell. We can consider the structure as a simple cubic with a basis of 8 atoms, at positions
