A unit cell is the smallest repeating unit of a crystal lattice that contains all the symmetry elements of the crystal.

The crystal structure describes the arrangement of atoms, molecules, or ions in a crystal lattice.

The unit cell is the smallest repeating unit of a crystal lattice that contains all the symmetry elements of the crystal.

A crystal family is the set of all crystal planes that have the same Miller indices.

Bragg's law relates the wavelength of X-rays to the scattering angle in a crystal lattice.

The energy bands in a solid are formed by the overlapping of atomic orbitals.

The energy gap between the valence band and the conduction band in a semiconductor is called the band gap.

The energy level at which the probability of finding an electron is exactly 50% is called the Fermi level.

The minimum energy required to remove an electron from a solid is called the work function.

The number of energy states available per unit volume in a solid is called the density of states.

The presence of impurities or defects in a crystal lattice can create color centers, dopants, and vacancies.

Color centers are created by the presence of both impurities and defects in a crystal lattice.

Dopants are intentionally added to a crystal lattice to change its electrical, optical, and magnetic properties.

Vacancies in a crystal lattice are created by the removal of atoms or molecules.

Solid-state chemistry is a branch of chemistry that deals with the properties, behavior, synthesis, and characterization of solids.
