Crystal structure of Diamond

Crystal structure of Diamond. Diamond structure is like a face-centered cubic(FCC) lattice. Each carbon atom joins four other carbon atoms in regular tetrahedrons. A tetrahedron has four faces and six edges. It is like an Egyptian pyramid in which the base is a triangle instead of a square. .

Crystal Structure

Crystal Structure. A “ unit cell ” is a subdivision of the lattice that has all the geometric characteristics of the total crystal. The simplest choice of this repeating combination of the atoms on a set of lattice points is called the unit cell.
