  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.

  3. Crystal structure - Wikipedia

    en.wikipedia.org/wiki/Crystal_structure

    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.

  5. Crystal system - Wikipedia

    en.wikipedia.org/wiki/Crystal_system

    The diamond crystal structure belongs to the face-centered cubic lattice, with a repeated two-atom pattern.. In crystallography, a crystal system is a set of point groups (a group of geometric symmetries with at least one fixed point).

  6. Diamond cubic - Wikipedia

    en.wikipedia.org/wiki/Diamond_cubic

    The atomic packing factor of the diamond cubic structure (the proportion of space that would be filled by spheres that are centered on the vertices of the structure and are as large as possible without overlapping) is , [3] significantly smaller (indicating a less dense structure) than the packing factors for the face-centered and body-centered ...

  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. [3]

  8. Supercell (crystal) - Wikipedia

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

    Some different supercells for 2D cubic crystal. Both diagonal and non-diagonal supercells presented. In solid-state physics and crystallography, a crystal structure is described by a unit cell repeating periodically over space. There are an infinite number of choices for unit cells, with different shapes and sizes, which can describe the same ...

  9. Tungsten - Wikipedia

    en.wikipedia.org/wiki/Tungsten

    The former has a body-centered cubic structure and is the more stable form. The structure of the β phase is called A15 cubic ; it is metastable , but can coexist with the α phase at ambient conditions owing to non-equilibrium synthesis or stabilization by impurities.
