What is the unit cell of diamond classified as? (2022)

Step 1: Understand what a unit cell is. A unit cell is the smallest repeating unit in a crystal structure.
Step 2: Learn about the diamond structure. Diamond is a form of carbon where the atoms are arranged in a specific pattern.
Step 3: Identify the type of lattice in diamond. The diamond structure is based on a face-centered cubic (FCC) lattice.
Step 4: Recognize that the FCC lattice has atoms at each corner and the center of each face of the cube.
Step 5: Note that in the diamond structure, there are two carbon atoms in the unit cell, which is referred to as a 'basis'.
Step 6: Conclude that the diamond structure is classified as a face-centered cubic (FCC) lattice with a basis of two carbon atoms.
