What is Unit Cell?
A unit cell is the smallest repeating structural unit that defines the structure of a crystal lattice. When repeated in three dimensions, unit cells build up the entire crystal. The unit cell is defined by its lattice parameters: edge lengths (a, b, c) and angles (α, β, γ). There are seven crystal systems with different unit cell geometries and 14 Bravais lattices.
